1/4-20X5/8 Phillips Truss Machine Screw Fully Threaded Black Oxide. Machine Screws are designed to go through a hole or nut that is pre-tapped to form a mating thread for that screw. Truss head screws are weaker than pan or round heads but preferred in applications where minimal clearance exists above the head. Modified truss heads offer low clearance and an extra large bearing surface. Commonly used to attach metal lathe to metal studs.
