Blue-White Zinc Plated Pan Head With Pad Self-Tapping Screw

1. Applicable fields and product standards

The integrated pan headflat washer structure disperses pressure during tightening and prevents the workpiece from being crushed and deformed. It is mostly used in the assembly of electrical chassis, plastic accessories, iron sheets, furniture hardware, door and window accessories, and its products are exported to Southeast Asia, the Middle East, and the African hardware market. Small holes need to be pre-drilled before use, and they rely on full-thread self-tapping locking. They are commonly used fasteners for the assembly of home appliances and light industrial equipment.

2. Raw materials and production technology

The raw material is high-quality carbon steel. The production process is: raw material rough drawing, annealing, phosphating, fine drawing, cold heading, point forming, thread rolling, heat treatment processing, zinc plating, washer assembly, packaging, eleven processes, integrated pan headflat The washer and screws are formed in one piece, eliminating the need for a separate gasket selection process and improving assembly efficiency; the Phillips recess is formed to a standard, and the matching Phillips screwdriver is not easy to slip and chip; the thread profile is sharp and uniform, and it is not easy to slip and crack when screwed into plastic, thin iron, and wooden substrates. The blue zinc coating is uniform and dense.

3. Product core advantages

Integrated widened flat washer structure: It comes with a large-diameter washer, which has a larger pressing force area, and it locks firmly without loosening, effectively protecting thin panels and plastic parts from being damaged by screws.

Universal fastening for multiple base materials: suitable for cold-rolled iron sheets, PVC plastics, solid wood, density boards, home appliance casings, and interior hardware.

Flexible selection of multiple coatings: standard blue-white zinc plated is universal; zinc plated color zinc plated is optional; black oxide version is used for concealed assembly inside the equipment.

4. Quality control warehousing and supporting services

All specifications are in stock, regular orders are dispatched within 48 hours, and both sample and full-container orders are accepted. The factory conducts random checks on flange flatness, notch strength, thread accuracy and coating quality, and rejects defective products with deformation and incomplete thread patterns. It can be supplied in complete sets with various self-tapping screws and self-drilling screws, providing one-stop fastening kits; it supports customized nonstandard lengthened screws according to incoming samples, and stable production capacity ensures long-term replenishment for customers.
