Color Zinc Plated Hex Flange Wood Screw With Washer

1. Applicable fields and product standards

This product has a hex flange integrated pad structure, focusing on solid wood keels, anti-corrosion wooden planks, wooden house frames, wooden fences, and outdoor furniture fastening. With its own sealing gasket, it takes into account both indoor home decoration and outdoor wooden projects. The products are exported to the building materials markets in Southeast Asia, the Middle East and Africa all year round. No pre-drilling is required, the coarse thread engages strongly with wood, and it is a universal fastening accessory for wood structure engineering.

2. Raw materials and production processes

High-quality carbon steel raw materials are selected. The production process includes ten processes: raw material rough drawing, annealing, phosphating, fine drawing, cold heading, thread rolling, heat treatment modulation and processing, zinc plating, washer assembly, and packaging. The flange and the gasket are integrated, and the coarse thread profile is wide and thick. When screwed into solid wood, it is not easy to split the wood or slip the thread;

3. Product core advantages

Integrated flange sealing structure: comes with a waterproof pad, which is sealed and waterproof after locking. The use of outdoor anti-corrosion wood prevents rainwater from penetrating into the screw seams and cracking.

Coarse teeth for strong wood gripping: Coarse pitch teeth, enough depth to eat wood, strong pull-out resistance, long-term use of wooden houses and plank roads are resistant to loosening and fall off.

Color zinc plated outdoor anti-corrosion: color zinc plated has outstanding performance and is preferred in rainy outdoor scenes. Its multiple coatings are suitable for indoor dry conditions.

4. Quality control warehousing and supporting services

The full range of specifications are always in stock, regular orders are dispatched within 48 hours, and large-volume engineering and full-container export orders can be accepted. The factory conducts random inspections of flange flatness, threads, and coatings, and rejects defective products with chipped heads and incomplete tooth patterns. It can be supplied in complete sets with various types of self-tapping screws and self-drilling screws; it supports customized lengthened nonstandard wood screws according to incoming samples, and stable production capacity ensures long-term supply of wood structure projects.
