Self-Tappers and Self-Drillers

Washered Hexagon Head Self Drilling Screws


We can supply a range of hexagon head self-drilling screws, with options on 16mm and 19mm diameter washers. Options include a selection of sizes (diameters and lengths), and types. Designs include light and heavy section screws, gash point, high thread, and stitching screws.

Hexagon head self-drilling screws are used for fixing steel to steel. Their uses span many applications across industrial and commercial applications, including roofing, ductwork, steel framework, and HVAC, as examples. The self-drilling capability saves time and ultimately cost. The washer is designed to not only spread the load out over a greater area, but also provide a waterproof seal, thanks to the bonded EPDM rubber surface.


Available in materials and finishes such as stainless steel and bright zinc plated (BZP).
