4-40 x 1/4 UNC Phillips Truss Head Machine Scr in A2 Stainless - ASME B16.6.3-2003

Philips Truss Head Machine Screws (UNC) have a wide and shallow domed shape, which can negate the use of a washer. The head shape also gives a larger contact area with the surface, which means a snag free fitment and helps guard against tampering. For use either in a pre-tapped hole or nut assembly. Ideal for sheet metal projects and applications where there is minimal clearance, such as sliding supports in draws and cabinets. Imperial Unified Coarse thread version. Phillips drive is x-shaped for installation with a Phillips screw driver.
