Timco - S/Tapping Screw PZ, Pan Head, Zinc Plated - 4 x 3/8

The Timco S/Tapping Screw PZ is a high-quality, self-tapping fastener engineered for robust and reliable metal-to-metal fastening applications. Designed with a pan head, these screws provide superior clamping force and a flush finish, making them ideal for sheet metal work, assemblies, and repairs where a secure and neat attachment is paramount.

Crafted from durable carbon steel, each screw features a specialised self-tapping thread with a 60° profile. This design ensures smooth and effortless insertion into pre-drilled pilot holes in metal, reducing the risk of thread stripping and ensuring a tight, vibration-resistant fit. The screws are finished with a Trivalent Chromium (Cr3) zinc plating, offering excellent corrosion resistance for both indoor and outdoor use, protecting the integrity of the joint over time.

Conforming to the rigorous BS 4174:1972 standard, these fasteners guarantee consistent quality, dimensional accuracy, and performance you can trust. The Pozi (PZ2) drive recess ensures positive engagement with the appropriate screwdriver bit, minimising cam-out and allowing for higher torque application without damaging the screw head.
