Machine Screw Truss Slot (Bulk Carton)
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 downward pressure to drive slotted parts than it does with cross recessed openings.
