The Draper 5 Piece 3/8" Drive Spline Socket Bit Set is a professional socket set designed for working with spline fasteners across a range of automotive and mechanical applications. Each of the five socket bits measures 100mm in length, providing extended reach for accessing recessed or hard-to-reach spline bolts commonly found in modern vehicles and machinery. Manufactured from hardened and tempered chrome vanadium steel, these sockets deliver the strength and durability required for regular professional use. The bits themselves are crafted from sand blasted S2 silicon steel, a material specifically chosen for its toughness and resistance to wear when working with stubborn or corroded spline fasteners. Each socket features a knurled ring that enhances grip during operation, particularly useful when working with oily hands or in challenging conditions. The set arrives mounted on a steel socket retaining rail, keeping the sockets organised and readily accessible in your toolbox or workshop. This socket bit set is ideal for mechanics and technicians working on vehicle brake systems, suspension components, and other assemblies where spline fasteners are specified. The range of sizes from M5 to M12 covers the most commonly encountered spline bolt specifications in automotive and light industrial maintenance work.
