Description
Overview:
The Timco Hex Self-Drilling Screw 5.5 x 25 is a robust fastener for fixing metal sheets and panels to light section steel. Made from hardened steel with a corrosion‐resistant plated finish, it combines a hexagon head for a secure drive with a self‐drilling tip that removes the need for pilot holes. At 5.5 mm diameter x 25 mm length (approximately 0.22 in x 0.98 in), it is sized for reliable grip and clamping force in thin-gauge steelwork. Designed for steel up to 5 mm thick (approximately 0.20 in), it suits roofing, cladding, and general fabrication. Supplied in a pack of 100 for site efficiency and consistency. Manufacturer: Timco. Manufacturer Part Number (MPN): 903 2026.
