Oil Drain Sump Plug Key Set 14pc Universal Hex Square Spline

A 14-piece oil drain sump plug key set for removing and refitting a wide range of sump plugs during oil changes and routine servicing. It includes hex, square and spline profiles, making it a practical choice for covering different vehicle fittings without relying on a single drain plug tool.

Used for garage work, workshop servicing and home vehicle maintenance, this set helps when draining engine oil on cars and vans fitted with different sump plug types. It suits mechanics, mobile technicians and DIY users who work across mixed makes, including common European and Japanese vehicles. The range of key styles makes it useful when servicing BMW, Ford, Volkswagen, Mercedes and other listed makes where drain plug fittings can vary from one model to another.

For use with a 17mm socket or spanner, the keys are straightforward to fit into the plug before loosening or tightening during service work. The set includes hex keys from 8mm to 17mm plus 3/8in, square keys from 8mm to 13mm, and an M16 tamperproof spline key. That spread helps cover common sump plug fittings and is useful for regular maintenance where you want the right key close to hand rather than stopping a job to search for alternatives. Keeping the different profiles together in one set also makes repeated servicing work more organised.
