Truss Head Screw

A truss head screw has a wide, low-profile head with a slotted drive. It spreads the load over a larger area than a standard pan head.

A truss head screw has a wide, low head that spreads load over a soft or thin surface. It takes a slotted screwdriver and often a washer under the head. It suits sheet metal, plastics and trim work, and it can be matched with a nut or driven into a tapped hole.

This kind of screw is often made in stainless steel 304 or 316. Grade 304 suits general use and grade 316 gives better corrosion resistance.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and check the head, slot and thread on receipt. Confirm the dimensions and material grade against the order.
