510 Piece Countersunk Self Tapping Screw Assortment

The Sealey 510 Piece Countersunk Self Tapping Screw Assortment is a comprehensive set of professional-grade fasteners designed for metalwork, sheet material fixing and general trade applications. This organised collection features DIN 7982 standard self-tapping screws with countersunk Pozi heads, providing a reliable fastening solution across a range of common sizes. Supplied in a practical partitioned storage box, this assortment keeps fixings organised and readily accessible on site or in the workshop. The selection includes six different size combinations ranging from 3.5mm to 4.8mm diameter, with lengths from 16mm to 38mm, ensuring you have the right screw for various fixing depths and material thicknesses.
