Truss Head Screws

Truss Head Screws are designed with an extra-wide, slightly domed head that provides a larger bearing surface compared to standard screw heads. This low-profile, rounded head helps to distribute load evenly and minimize surface damage, making them ideal for sheet metal work, plastic assemblies, and electrical applications.

The wide head also covers oversized holes or slots effectively, adding both strength and aesthetics to the finished assembly. Truss head screws are commonly available with Phillips, slotted, or combination drive types, and can be used in both decorative and functional applications.

Available in metric and imperial sizes, these screws are manufactured in a variety of materials including stainless steel, carbon steel, and zinc-plated steel, offering options for both strength and corrosion resistance.
