Philips Drive Truss Head Self-Tapping Screw – 4.2mm x 1-1/4″

Description

The 4.2mm x 1-1/4″ Philips drive truss head self-tapping screw is a versatile fastener suited to a wide range of sheet metal, electrical enclosure, and plastic panel applications. The oversized truss head provides a large bearing surface that resists pull-through in softer or thinner materials, making it especially suitable for polycarbonate panels, thin aluminium sheeting, and PVC. The sharp self-tapping thread cuts cleanly through pre-drilled or punched holes without needing a tap, while the Philips recess offers universal bit compatibility. The bright zinc plating provides adequate corrosion resistance for interior and sheltered exterior use. These screws are popular in electrical installation, HVAC, and light fabrication work. Sold in bulk packs for trade and contractor use.
