Stainless Steel Phillips Truss Head Machine Screws

Diameter - Thread Pitch: 5/16"-18

Stainless Steel Phillips Truss Head Machine screws feature an oversized head with an undercut bottom and a low profile domed top. Phillips Truss Head Machine Screws are also known as Mushroom Head Screws, due to the size and undercut of the screw head. Truss Head Screws have a lower profile than Pan Head Screws, which is meant to prevent tampering or accidental loosening, as well as distributing the force of the installation over a wider diameter. Truss Head Screws in this selection feature a Phillips Drive and an 18-8 Stainless Steel Finish, making them corrosion and rust resistant in applications exposed to fresh water moisture. The nature of the head on these screws, as well as the 18-8 Stainless Steel material ensure a durable fastener assembly.
