The Sealey 600 Piece Countersunk Self Tapping Screw Assortment is a comprehensive fastener kit designed for professional tradespeople and contractors requiring a reliable selection of self-tapping screws for workshop or site use. This assortment contains 600 countersunk Pozi head screws manufactured to DIN 7982 standards, covering 11 different size combinations ranging from 3.5mm to 4.8mm diameter and 16mm to 38mm in length.

All screws are supplied in a sturdy partitioned storage box that keeps each size organised and readily accessible, making it ideal for mobile tradespeople and service engineers. The countersunk profile ensures a flush finish on sheet metal, plastic, and composite materials, whilst the Pozidrive head provides reliable torque transfer and reduces cam-out during installation.
