The Sealey 1/2" Drive Impact Spline Socket Bit Set is a professional-grade socket set designed for use with impact tools across automotive and engineering applications. Manufactured from chrome molybdenum steel with a phosphate finish, this set delivers the strength and corrosion resistance required for demanding workshop environments. The spline socket design provides superior grip on fasteners compared to standard hex sockets, making it particularly effective for removing damaged or rounded bolts. Each socket features colour-coded identification rings for quick size selection during busy work periods, whilst the 1/2" square drive ensures compatibility with most professional impact wrenches and drivers. Ideal for mechanics, plant engineers and mobile technicians, this eight-piece set covers the most commonly used metric spline sizes from M5 through to M18. The included socket rail keeps the set organised and readily accessible in toolboxes or workshops. As part of Sealey's Premier Han
