Tackling fasteners across modern automotive and engineering work increasingly requires more than a basic socket set TRX-Star, Security TRX-Star, Hex, Ribe, and Spline profiles are all common in vehicle assembly, and having every size to hand in both short and long formats avoids the frustration of hunting for the right bit mid-job. The Sealey AK21974P 74-piece Premier bit set brings all of those profiles together in a single, organised storage case. All 74 bits are manufactured from high-quality S2 steel with a zinc phosphate finish and are hardened to 58-62 HRC before tempering for added strength, making them suitable for daily professional use. Every size is supplied in both 30mm and 75mm lengths, giving you the reach you need in confined areas without sacrificing control on accessible fasteners. The set covers TRX-Star bits T20 through T60, matching Security TRX-Star variants T20H through T60H, Hex sizes 4mm to 12mm, Ribe sizes M5 to M14, and Spline sizes M5 to M12 all in both lengths. Two drive adaptors are included: 3/8" square to 10mm hex and 1/2" square to 10mm hex, both in Chrome Vanadium steel, allowing the bits to be used with 3/8" and 1/2" square drive tools. The storage case features an inclined tray for quick and easy bit identification and selection. Backed by a lifetime guarantee.
