The thing I use the most in my toolkit is my Silca HX-One home wrench set, yet I never bring it on the road with me because I’m afraid of losing some of the tiny bits in the black hole that is my truck. After the success of the HX-One home kit, Silca announced their HX-Two travel kit. These are not your standard hex wrenches. Not at all. This is Silca after all.
These wrenches are heat treated with a 9 step process, with a high grip polymer coating over high-engagement satin chrome. After over two years of heavy use, my HX-One wrenches still look brand new. The hex keys in the set, which include 10, 8, 6, 5, 4, 3, 2.5, 2, and 1.5mm, and Torx® keys include T30, T27, T25, T20, T15, T10, T9, T8, and T7. See more at Silca.
