CORET Wafer Head 19mm Black Self Tapping Screws (55PCS) Wide Truss for Sheet Metal Aluminium Wood Plastic - M4.2mm x

FINE THREAD WITH SHARP TIP: Cross large head fine thread self-tapping screws are engineered to make fastening quick. The sharp point helps the screw start easily in the material, while the Phillips drive allows controlled, reliable use. CARBON STEEL & PHOSPHATE COATING: Wafer head screw fasteners are made from hardened carbon steel material and feature a black phosphate finish that helps reduce surface oxidation. LOW-PROFILE WAFER HEAD DESIGN: Wide flat bearing head screws help improve stability under load and movement. The head profile distributes contact pressure across the mounting area, reducing surface damage for clean installation results. MULTI-PURPOSE USE: Wafer head screws are suitable for aluminum and sheet metal, plastic components, furniture assemblies and interior panels, as well as fastening plasterboard, drywall tracks to thin metal. ADDITIONAL FIXING APPLICATIONS: M4.2mm x 19mm screws are also suitable for general indoor fixing tasks in home improvement, DIY projects and workshop use, including woodworking, light construction and metal tasks.
