Needed access to oni didn’t want to carry another screwdriver this fits in my 216 when needed.

Amazing will use agian

It has two ends of different sizes, both are 34;security34; or 34;tamper-proof34; style hex - like an Allen Wrench but with a hole in the middle. For those locks/bolts that have a hex indentation with a pin in the middle. Mostly used for telecom cabinets. Fits in the end of a can-wrench or other 5/16 hex deep-socket like a spark-plug socket bit. Useful enough, but you can't get much leverage on a can wrench with your bare hands so I prefer to just use the 5/1634; security hex wrench that I bought in another kit that includes more wrench sizes FOR LESS MONEY:nbsp; Bondhus 48332 Tamper Resistant Hex L-Wrenches, Set of 8

Works good
