Screws Meaning in English for Fastener Buyers | Hebei Wotu Fastener Manufacturing Co., Ltd.
In English, “screws” usually means threaded fasteners that join materials by turning into a pilot hole, a pre-formed thread, or the material itself. For purchasing, the word is too broad on its own; the important decision is which screw type matches the material, load, head style, drive, coating, and installation method.
If you are translating a drawing, preparing an inquiry, or comparing fastener quotations, describe the screw by function first: self-tapping, self-drilling, machine screw, wood screw, chipboard screw, roofing screw, or another defined type. That prevents confusion between similar fasteners that look alike but install very differently.

When comparing screw options, focus on the fastener’s job: how it enters the material, how the head seats, how the drive transfers torque, and how the finish suits the service environment. Clear terminology reduces the risk of receiving a fastener that matches the English name but not the actual assembly.
| Criterion | What To Check | Why It Matters | Buyer Tip |
|---|---|---|---|
| Term used in the enquiry | Confirm whether the buyer means general screws, self-tapping screws, self-drilling screws, fiberboard screws, or another screw type. | The English word “screws” is broad. A loose translation can lead to the wrong point style, thread form, head type, or installation method. | Ask: “By screws, do you mean standard machine/wood screws, self-tapping screws, or self-drilling screws for your application?” |
| Application material | Identify the materials being joined, such as metal to metal, metal to wood, timber, fiberboard, plastic, or roofing sheet. | Screw meaning in English often depends on use. A screw for fiberboard furniture is not specified the same way as a screw for metal roofing or sheet metal assembly. | Ask: “What materials will the screw fasten, and is the hole pre-drilled or made by the screw?” |
| Head drive description | State the head shape and drive in plain English, such as countersunk head with cross recess, hex washer head, pan head, or flat head. | Head and drive affect surface finish, tool fit, seating, and installation speed. Translation errors here are common in purchase requests. | Ask: “Should the head sit flush with the surface, clamp on top, or work with a washer or sealing gasket?” |
| Thread and point function | Separate the thread type from the point type: coarse thread, fine thread, thick thread, tapping point, or drill point. | Threads grip the base material; points decide how the screw enters it. Mixing these terms can cause stripping, poor pull-out resistance, or slow installation. | Ask: “Do you need the screw to cut its own thread, drill its own hole, or only fasten into an existing hole?” |
| Size wording in English | Clarify diameter, length, and any gauge or inch wording before quoting or ordering. | English screw descriptions may use metric sizes, inch lengths, or gauge numbers. The same phrase can be misunderstood if the measuring system is not stated. | Ask: “Can you provide the screw diameter, total length, and measuring standard, or share a drawing or sample photo?” |
The practical difference is that “screw” describes the general fastener, while terms such as “self-tapping screw” or “self-drilling screw” describe how it forms or uses the hole. A self-tapping screw cuts or forms its own mating thread in a prepared hole or soft material; a self-drilling screw has a drill point that can make the hole before the threads engage. That distinction affects tool setup, pilot hole planning, holding strength, and installation speed.
Head and drive terms also change the meaning. “Countersunk head” means the head is designed to sit flush with the surface; “pan head,” “hex head,” and “wafer head” describe different bearing areas and appearance. “Cross,” “Phillips,” “Torx,” and “hex” describe the drive used to turn the screw, not the thread. A clear English specification should combine these terms instead of relying on the word “screws” alone.
Start with the material pair. Metal-to-metal work may need self-drilling or machine screws depending on whether the hole is already prepared. Wood, fiberboard, and furniture panels usually need thread geometry that bites without splitting or stripping the board. Roofing and sheet applications add sealing and washer contact as part of the decision, not just screw length.
Match the point and thread to the installation process. A drill point can save a separate drilling step, but it is not automatically better for every assembly. A tapping thread can give reliable engagement when the hole size and material thickness are controlled. A coarse thread may grip softer material well, while the wrong pilot hole can reduce holding power or crack the workpiece.
Do not choose only by visible size. Two screws with the same length and head shape can have different point styles, thread pitch, surface treatment, and intended substrate. For procurement documents, include head type, drive type, nominal diameter, length, thread style, point type, coating or finish, washer requirement if any, and the material being fastened.
A useful next step is to send the application rather than just a name: the two materials being joined, the required head appearance, whether holes are pre-drilled, and the environment where the fastener will be used. Hebei Wotu Fastener Manufacturing Co., Ltd. can then confirm which screw description fits the inquiry and what details still need to be specified.
| Criteria | Importance | Description | Example Options |
|---|---|---|---|
| How the hole and thread are formed | Critical for tool setup, installation time, and thread engagement. | A self-tapping screw uses a prepared hole or forms a mating thread in suitable material. A self-drilling screw uses a drill point to start the hole before its threads engage. | Use a tapping design for a controlled pre-drilled assembly; consider a drilling point where a separate drilling step is not wanted and the material is suitable. |
| Material and joint type | The substrate determines whether the point and thread can achieve reliable grip without excessive damage. | Metal-to-metal, metal-to-wood, furniture board, and roofing applications place different demands on thread shape, point design, and head contact. | A furniture-panel assembly may need a board-friendly coarse thread, while a sheet-metal joint may need a thread and point matched to the metal. |
| Head style and drive | These affect surface appearance, seating, bearing area, and the tool needed for installation. | Countersunk heads are intended to sit flush when the material and recess allow it; pan, hex, and wafer heads provide different seating arrangements. Cross, Torx, and hex identify the drive, not the screw type. | Choose a countersunk head for a flush furniture surface, or a hex head where an external bearing surface is preferred. |
| Thread, length, and engagement | Correct engagement supports holding power while limiting breakthrough, splitting, or interference with hidden parts. | Length should reflect the materials and joint geometry, not just the visible thickness. Thread style and pilot-hole size also influence grip, especially in softer materials. | A longer screw is not automatically stronger if it exits the workpiece or has insufficient thread engagement in the intended substrate. |
| Finish and sealing requirements | The surface treatment and any washer or seal affect suitability for the service environment and joint sealing. | Specify the required finish according to the surrounding conditions and confirm whether the assembly needs a washer or sealing contact. Finish alone does not define the screw's mechanical or installation function. | A roofing application may require a compatible washer and sealing arrangement, while an indoor furniture assembly may prioritize appearance and clean seating. |

For furniture assembly, the priority is often clean seating and strong grip in board material; for sheet metal, it may be drilling performance and thread engagement; for roofing, sealing contact and correct washer compression become central. The right screw description should reflect the use case before size and finish are finalized.
Fiberboard screws are selected based on more than screw size alone. For furniture assembly and board-based applications, buyers need to match the screw structure with the characteristics of fiberboard, MDF, and similar engineered wood materials. A suitable specification should consider thread design, head style, screw length, diameter, installation method, and application requirements. For buyers sourcing […]
#4 self tapping screws should not be purchased from the “#4” designation alone. For a usable B2B specification, the buyer still needs the actual screw diameter, thread form or pitch, overall length, substrate, pilot-hole condition, head and drive style, material, surface finish and quantity. This matters because suppliers may use different naming systems. Wotu Fastener’s […]
A request for “1 1/2 self tapping screws” is incomplete until the buyer confirms what the 1 1/2 dimension refers to and how the screw will engage the base material. If 1 1/2 inch is the required overall length, that is only one part of the specification. Diameter, thread, head, drive, substrate, pilot-hole condition and […]
Direct answer: Choose a self-drilling screw when the fastener must create a hole through a verified metal stack before its threads engage. Choose a self-tapping screw when the assembly already has a correctly sized pilot hole or when the selected thread is intended to form or cut into the specified substrate. The decision must also […]
Direct answer: Correct screw length does not guarantee a watertight metal-roof connection. Self tapping roofing screws can leak because of incorrect washer compression, enlarged or stripped holes, insufficient thread engagement, panel movement, or an unsuitable coating-and-washer system. Buyers should diagnose the complete installed connection—including panel profile, support thickness, point type, washer condition, and exposure—rather than […]
Direct Answer: A self-drilling screw has a drill-shaped point that creates a hole and then forms mating threads in a suitable material. A self-tapping screw forms or cuts mating threads but may require a correctly sized pilot hole. Selection depends on substrate type and thickness, joint stack, point geometry, installation tool, finish and application testing—not […]
It is a general term for a threaded fastener driven by turning. The specification should add the type, such as machine screw, wood screw, self-tapping screw, self-drilling screw, or roofing screw, along with the size and head details.
No. A self-tapping fastener forms or cuts threads in a prepared hole or suitable material, while a self-drilling fastener has a drill point that can create the initial hole before thread engagement. Choosing between them depends on the material, thickness, hole preparation, and installation process.
Usually not without checking the thread, point, and head design. A coarse-thread fastener may suit wood or fiberboard, while sheet metal may require a tapping or drilling point matched to the metal thickness; using the wrong design can reduce grip or damage the material.
No. “Cross” describes the drive recess, not the thread, point, material, or application. A complete description might combine a cross drive with a countersunk head, a specified diameter and length, a particular thread, and a substrate such as furniture board or sheet metal.
State the materials being joined, whether holes are pre-drilled, the required head and drive, nominal diameter and length, thread or point style, finish, and any washer or sealing requirement. If the English name is uncertain, include a drawing, sample, or application description and ask Hebei Wotu Fastener Manufacturing Co., Ltd. to confirm the terminology and remaining details.
Send the materials being joined, the required screw type or application, and any known size, head, drive, finish, or washer requirement so the inquiry can be checked accurately.
