Hex Head Self Drilling Screws for Light Section Steel

This 4.8mm x 13mm hex head self drilling screw is the shortest option in the 4.8mm diameter range, designed for fixing thin roofing sheets to light gauge steel where minimal penetration depth is required. The compact size makes it ideal where screw length must be carefully controlled, and no pre-drilling is needed. Despite its short length, the hex head with integral washer ensures a reliable clamping action, and the coarse thread provides firm engagement in light section steel. Zinc plating offers good protection against corrosion for external roofing applications. Supplied in a pack of 1,000 — excellent value for large-scale projects.
