Timco A2 Stainless Steel Self-Tapping Screws, PZ Countersunk, 4.2x25mm (200pk)
Timco A2 stainless steel self-tapping screws for metal. Corrosion-resistant, PZ countersunk head, 4.2x25mm – 200pc pack. Ideal for outdoor/marine use.
The Timco A2 Stainless Steel Self-Tapping Screws are premium fasteners designed for secure metal stitching and attachment applications. Manufactured from austenitic A2 stainless steel (304 grade), these screws offer exceptional corrosion resistance, making them ideal for outdoor use or environments with high moisture or chemical exposure. The screws require a pre-drilled hole for installation.
These countersunk-head screws provide a discreet, flush finish when used with pre-countersunk holes, while the 60° self-tapping thread ensures smooth and easy insertion. Compatible with PZ2 bit drivers, they maintain high strength and durability even in demanding conditions.
The 4.2mm thread diameter and 25mm length (1-inch equivalent) make them versatile for various metal-fixing tasks, from HVAC installations to marine applications. Their AB point enhances penetration efficiency, reducing the risk of material damage during installation.
