White Zinc Plated Hex Head Self-Drilling Screw

1. Applicable fields and product positioning

This product focuses on fastening scenarios for indoor needs, and is suitable for splicing light steel keels, equipment sheet metal parts, factory lining steel sheets, guardrail frames, and electromechanical equipment thin panels. The products are exported to the hardware and building materials markets of many countries. The product is more cost-effective, specially designed for indoor dry environments, and can also be used for open-air waterproof roof construction.

2. Material Selection and Production Process

Selected raw materials from large steel mills, quenching treatment, strong drilling tail cutting performance, production process: raw material rough drawing, annealing, phosphating, fine drawing, cold heading, point forming, thread rolling, heat treatment modulation processing, zinc plating, washer assembly, packaging eleven processes, flange integrated stamping molding comes with steel washers to disperse the compression stress during assembly and protect the workpiece surface from being crushed; thread precision thread rolling, the pitch is uniform, and the engagement with the plate is firm, and it is resistant to loosening under long-term vibration conditions.

3. Product core advantages

Efficient drilling-free: The same self-drilling structure directly drills through thin steel sheets, eliminating the need for pre-drilling processes. Indoor mass assembly effectively improves construction efficiency. It is suitable for all types of cold-rolled steel sheets and zinc plated thin panels.

High cost-effectiveness: The advantage of purchasing in large quantities is obvious. It is a general-purpose economical fastener for indoor infrastructure and hardware assembly.

Multi-plating selection: blue-white zinc plated is the most versatile, color zinc plated is available for indoor wet workshops, and black oxide is available for concealed assembly in the equipment cavity, matching the needs of different working conditions as needed.

4. Quality control and supporting services

The full range of specifications in stock is sufficient, regular sizes can be quickly arranged within 48 hours, and sample orders and full-container export orders can be accepted. The dimensional accuracy, drill point strength, and coating adhesion are randomly inspected before leaving the factory, and defective products with deformation and thread damage are strictly controlled. It can be supplied in complete sets with our waterproof drill point and matching nut flat washer, providing a complete set of fastening accessories in one stop; it supports customized special-shaped specifications according to incoming samples, and stable mass production can meet the long-term replenishment needs of overseas traders.
