Over-driving compresses the washer excessively and causes it to extrude beyond the screw head, which can create a water path into the building rather than away from it - the correct torque leaves the washer slightly compressed but not extruded.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in steel with organic polymer coating for corrosion resistance, in the lengths needed for standard profiled sheet roofing at the DIY Hardware Store.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHex-head self-drilling screws for metal and profiled sheet roofing\u003c\/li\u003e\n\u003cli\u003eBonded EPDM rubber washer seals fixing hole against water ingress\u003c\/li\u003e\n\u003cli\u003eSelf-drilling tip eliminates pre-drilling into steel purlins\u003c\/li\u003e\n\u003cli\u003eDo not over-drive - washer must not extrude beyond head\u003c\/li\u003e\n\u003cli\u003ePolymer-coated for outdoor corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSuitable for agricultural, industrial, and domestic outbuilding roofing\u003c\/li\u003e\n\u003c\/ul\u003e","products":[{"product_id":"clear-spacer","title":"Clear Spacer for Coorugated Roofing Sheets (Sold as singles)","description":"\u003cp\u003eAchieve optimal spacing and prevent crushing of your corrugated roofing sheets with our Clear Spacer.
