Socket Set 1/2in Drive Triangular M5-M12 Diesel Injector

A 5-piece triangular socket set for removing and fitting triangular profile tamperproof fixings used on Bosch diesel injector pumps. With a 1/2in drive and sizes from M5 to M12, it is aimed at service and repair work on compatible diesel systems and VAG TDI applications.

Used for injector pump work, diesel servicing and repair jobs where standard sockets will not fit triangular security-style fixings, this set suits garage work, workshop use and more involved vehicle maintenance. It is particularly relevant when working on Bosch injectors, injection pumps and VAG vehicles with TDI engines, helping mechanics and experienced DIY users deal with fixings that need the correct profile for safe removal and refitting.

Made from chrome vanadium steel, the set includes five tri-point sockets in M5, M6, M8, M10 and M12 sizes, with corresponding socket sizes of 8mm, 10mm, 12mm, 15mm and 16.5mm. The 1/2in drive format makes it suitable for use with common ratchets and workshop drive tools where a secure fit and controlled turning force are needed. The size spread covers several common injector and pump fixing sizes, which is useful for regular maintenance and helps avoid reaching for makeshift alternatives on specialist jobs.
