Bit Socket Set 54pc Tamperproof Torx Hex Spline 3/8in 1/2in

A 54-piece bit socket set for handling a wide range of tamperproof Torx, hex and spline fixings. Built around 3/8in and 1/2in drive sizes, it combines a hex socket set with Torx and spline bits for jobs where standard sockets or bits will not do the job properly.

Used for vehicle maintenance, garage work, workshop repairs and general servicing, this set suits anyone regularly dealing with internal drive fasteners on engines, brakes, trim, covers and other fitted parts. It is also useful for DIY repairs and trade work where tamperproof and specialist fixings come up, helping reduce delays when the right bit is needed for access or removal.

The set includes hex bits from 4mm to 12mm, spline bits from M5 to M12, and star bits from T20 to T55, each supplied in both 30mm and 75mm lengths. That gives you short bits for tighter access and longer bits where extra reach is needed around recessed or awkward fixings. With both 3/8in and 1/2in drive bit adaptors included, the set works across common ratchets and breaker bars already in a garage or workshop. The range helps cover many of the sizes regularly seen in maintenance and repair work, so there is less need to stop and search for separate bits mid-job.
