The Sealey 700 Piece Flange Head Self Tapping Screw Assortment is a comprehensive selection of black flanged screws designed for professional tradespeople and contractors. This BS 4174 compliant assortment provides a practical workshop solution, offering nine different size combinations to suit a wide range of metalworking and sheet metal applications. Each screw features a flange head design which increases the bearing surface area, distributing clamping pressure more evenly than standard self-tapping screws. This makes them particularly suitable for fixing thin gauge materials where pull-through might otherwise be a concern. The black finish provides basic corrosion resistance for interior applications. The assortment is supplied in a partitioned storage box, keeping the different sizes organised and easily accessible on site or in the workshop. With 700 pieces spanning diameters from 3.5mm to 4.8mm and lengths from 10mm to 25mm, this selection is ideal for sheet metal fabrication, HVAC installation work, electrical enclosure assembly, and general metal fixing tasks where drilling pilot holes is impractical.
