## Description

The Stanley FatMax Multi-Stack 55 Piece Impact Screwdriver Bit Set is a comprehensive bit set designed for tradespeople who need a versatile, impact-rated fastening solution across a wide range of applications. Built to withstand the demands of impact drivers, the bits feature a Flexible Torsion design that absorbs rotational stress, reducing the risk of bit breakage during heavy use. Precision machining ensures a reliable fit in screw heads, minimising cam-out and protecting fixings. A magnetic ring collar allows for single-handed screw positioning, making it particularly useful when working in tight or awkward spaces. The set covers the most commonly used drive types on site — Pozi, Phillips, Torx, and Hex — alongside 8mm and 10mm nut setters and a Torsion bit holder. A removable bulk storage case houses 20 loose Torx bits for quick access. The transparent lid makes it easy to identify contents at a glance without opening the case. Storage is handled by a robust stackable case compatible with the TSTAK and PRO-STACK interconnectable systems, ideal for contractors and tradespeople who prefer a unified, organised tool storage setup on the van or at the job site.
