Slotted round head 5/16-24 UNF zinc-plated screw is a TECTUL reference for light equipment, instruments, panels and maintenance where fine inch thread and a flat screwdriver are required. The actual lot reports carbon steel material, sale per unit and zinc-plated · inch thread family; the technical sheet separates it by 5/16-24 thread, slotted round head and zinc-plated finish. To buy without errors, validate head, drive, diameter or pitch, useful length and finish against the sample, drawing or existing nut. ASME B18.6.3 is used as a public reference for inch machine screws; DIN 6921 identifies hex flange bolts, and metric threads are validated against ISO or DIN when the drawing requires it. We do not publish a single torque or capacity because the result depends on base material, thickness, lubrication, coating, head bearing, vibration, grip length and tightening method.
