42 Piece 3 8" 1 2" Drive Impact Socket Bit Set

The Sealey 42 Piece 3/8" and 1/2" Drive Impact Socket Bit Set is a comprehensive impact driver accessory kit designed for professional tradespeople and serious DIY users. Manufactured from high quality impact grade S2 steel with a durable satin finish, this versatile set includes each bit size in both 36mm and 75mm lengths, providing flexibility for working in confined spaces or reaching deeper fixings. The bits feature heat treated CNC machined tips that reduce stress concentrations and prevent cam-out under load, ensuring reliable fastening even in demanding applications. The torsion design absorbs impact forces and transfers maximum torque to the fixing, whilst the hardened (58-62 HRC) and tempered construction delivers exceptional strength and longevity. Colour-coded sizing enables fast identification on site, saving valuable time during busy jobs. This socket bit set is ideal for automotive repair, engineering work, and general construction tasks where impact drivers are used. The comprehensive range includes TRX-Star, hex, and spline bits covering the most commonly used sizes, along with 3/8" and 1/2" square drive adaptors for compatibility with standard impact wrenches and drivers. The storage case features an inclined tray design for quick bit selection and secure transport between job sites.
