The Hozan C-160 has been offered by Hozan to discriminating mechanics since the early 80's. It serves two functions. One is to secure older style crank bolts and the other is the tightening of fixed gear hub bolts. The C-160 has a dual head that has a 14mm one side and a 15mm on the other. Simple switch flips up or down to set the ratchet in tighten or loosen mode.
The hardened steel stem will not bend, flex of break. The end of the stem has a durable, non-slip rubber coated grip. This is a professional-grade tool that is designed to last a lifetime.
