Toptul GAAL0912 Extra Long Type Hex Key Wrench Set 9pcs

I found the hex set (extra long - Allen keys) to be very useful in reaching those fasteners that are normally just out of reach with a conventional set, and when you can obtain the reach; its usually with the hex only partially indexed (leading you into trouble). The price is reasonable and the quality of the set is up there with the better known brands.
