Hex Head Self Drilling Screws for Light Section Steel

This 4.8mm x 19mm hex head self drilling screw is a versatile, smaller-diameter fixing suitable for attaching roofing sheets to light gauge steel in a range of standard applications. The 19mm length works well across a variety of thin sheet profiles, and the self drilling point removes the need for pre-drilling entirely. The hex head with integral washer distributes the clamping load effectively, helping to create a neat, secure fixing with reduced risk of sheet deformation. The coarse thread bites firmly into light section steel, and zinc plating ensures good corrosion resistance in external environments. Supplied in a pack of 1,000 for high-volume use.
