Hot Sale 40mm Truss Self Tapping Screw

The Truss head self-tapping screw is a specialized type of fastener designed for applications where a low-profile, wide head is required to distribute load and provide a secure hold. The "truss head" refers to the screw's unique head shape, which is slightly rounded with a large diameter and a low height. This design allows the screw to sit flush or slightly above the surface of the material, offering a larger bearing surface compared to other screw types, such as pan head or flat head screws.

Key Features:

1. Self-Tapping Design:
   The screw features sharp threads that cut into materials like metal, plastic, or wood as it is driven, eliminating the need for pre-drilled pilot holes. This makes installation faster and more efficient.

2. Wide, Low-Profile Head:
   The truss head provides a larger surface area, which helps distribute pressure evenly and reduces the risk of material damage, especially in softer materials like plastic or thin metal sheets.

3. Versatility:
   Truss head self-tapping screws are commonly used in applications where a secure hold and a smooth finish are required, such as in HVAC systems, electrical enclosures, roofing, automotive assembly, and construction.

4. Material and Coating Options:
   These screws are available in various materials, including stainless steel, carbon steel, and brass, often with coatings like zinc plating or galvanization to enhance corrosion resistance and durability
