Hex Head Self Drilling Screws for Light Section Steel

This 5.5mm x 32mm hex head self drilling screw offers a practical mid-length option for fixing roofing sheets to light gauge steel without the need for pre-drilling. The 32mm length provides good penetration through standard sheet profiles whilst keeping fixings neat and efficient. The integral washer beneath the hex head increases the bearing surface, spreading the clamping load and helping to create a more secure, weathertight fixing. Coarse threading ensures strong pull-through resistance in light section steel, and the zinc plating protects against corrosion in exposed roofing environments. Supplied in a pack of 500.
