Machine Screw Truss Head, Slotted

Machine Screw Truss Head, Slotted

Porteous II



Machine Screw Truss Slot: Has a low rounded top surface with a flat bearing surface greater in area than a round-head screw of the same nominal size. Weaker than pan or round heads but preferred in applications where minimal clearance exists above the head. Truss profile provides a trim, finished assembly appearance. Accepts standard blade screwdrivers. Requires less downoad pressure to drive slotted parts than it does with cross-recessed openings. *ZB - ZINC BLUE
