The Sealey 28 Piece 3/8" and 1/2" Drive Impact Socket Bit Set is a comprehensive impact-rated bit collection designed for use with impact drivers and wrenches. Manufactured from high quality impact grade S2 steel with a satin finish, each 36mm length bit features specially heat treated CNC machined tips that reduce stress and prevent cam-out under load, ensuring reliable engagement even in demanding applications. The torsion bit design absorbs impact forces and transfers maximum torque to the fixing, whilst the hardened (58-62 HRC) and tempered construction provides the strength required for professional use. Colour-coded for fast identification, this set includes an extensive range of TRX-Star, hex, and spline bits to cover the most common fastener types encountered by automotive technicians, mechanics, and general tradespeople. The set includes both 3/8" and 1/2" square drive adaptors with 10mm hex connections, allowing seamless compatibility with impact drivers. All 28 pieces are supplied in a durable storage case for organised transport and workshop storage, and the set is backed by a lifetime guarantee.
