The BlueSpot 10 PCE Metric T Handle Hex Key Set (2-10mm) is manufactured from chrome vanadium and features a heavy-duty ergonomic plastic grip. The set comes complete with a rack which has two mounting holes so that it can be easily fixed to a bench or wall. The rack also helps keep the hex keys in size order as each key fits neatly into its own space on the rack. The keys are also double-sided with one long part and one short.
