Zinc-plated round head contact screw is a TECTUL reference for contacts, terminals, small covers, electrical equipment and light assemblies where a zinc-plated round head is required. The actual lot reports carbon steel material, sale per unit and zinc-plated · inch thread family; the technical sheet separates it by zinc-plated round head in small sizes, distinct from the Phillips machine screw by its contact use and compact dimensions. 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 We do not publish a single torque or capacity because the result depends on base material, thickness, lubrication, coating, head bearing, vibration, grip length and tightening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.
