## Description

The Stanley FatMax Multi-Stack 32 Piece Impact Screwdriver Bit Set is a professional-grade bit set designed to handle a wide range of fastening tasks across multiple drive types and sizes. Engineered for use with corded and cordless drills and impact drivers, the bits feature a quick-change 1/4" (6.35mm) shank for fast, tool-free swaps on site. The 50mm torsion bits incorporate a flexible shaft specifically designed to absorb the shock of high-torque impact driving, reducing breakage and extending working life. Each bit is forged, ground, and precision machined for a secure fit in the fastener head, keeping cam-out and stripped screws to a minimum. The set covers Pozidriv, Phillips, Slotted, Torx, and Hex profiles across 25mm and 50mm lengths, along with nut drivers — making it a genuinely versatile addition to any tradesperson's kit. The set is supplied in Stanley's Multi-Stack case, which is designed to stack with other cases in the range for organised storage and straightforward transport between jobs.
