Bit Socket Set 1/2in Tamper-Proof VW Audi Gearbox Drain Plug

A 6-piece bit socket set for removing and fitting tamper-proof 12 point gearbox drain plugs and other security fixings. Made for use with a 1/2in drive, it covers a practical range of spline sizes commonly used on VW and Audi applications.

Used for gearbox servicing, drain plug removal and general VAG maintenance work, this set suits garage use, workshop servicing and home mechanics carrying out routine repairs. It is especially useful when working on plugs and fixings that need a tamper-proof 12 point profile, helping with access to the correct fitting without relying on improvised tools that can damage the fastener.

The set includes six bit sockets in M10, M12, M14, M16, M18 and M20 sizes, giving coverage for a useful spread of common security fixings. Each bit is 30mm deep, which helps when reaching into recessed drain plug positions or fittings where extra depth is needed for cleaner engagement. The 1/2in drive fit makes the set suitable for use with standard ratchets, breaker bars and workshop tools already in regular use. For repeated servicing work, having the main sizes together in one set helps avoid switching between mismatched bits and makes gearbox maintenance more straightforward.
