Spline Bit Socket Set M4-M18 9pc Impact Stubby 1/4 3/8 1/2in Drive

A 9-piece bit socket set for spline tamper proof fixings, covering sizes M4 to M18 in a low profile stubby format. Built for use with impact tools, it gives a compact option where standard-length bit sockets can be awkward to position.

Used for garage work, workshop repairs and general maintenance where spline security fasteners need removing or fitting, this set is especially handy when access is restricted around engine bays, brackets, covers and other tight areas. Suitable for use with air or electric impact guns, it suits mechanics, maintenance engineers and DIY users who need impact-ready spline bits for regular servicing and repair jobs.

The set uses one-piece construction for added strength and durability, with chrome molybdenum steel and a black phosphate finish for corrosion resistance in working environments. Stubby bit lengths help when clearance is limited, while the size spread covers smaller and larger tamper proof spline fixings across different tasks. With 1/4in, 3/8in and 1/2in drive bit sections included, it gives a practical range for common workshop use and helps avoid reaching for longer sockets where they simply will not fit.
