Rebuild a bicycle rear hub

Step 6 Remove the freehub lock-screw

Since I do not have the appropriate 12-point key for this bolt, I used a pair of allen-wrenches paired-up in the fashion shown. Find the combination that provides the tightest fit to minimize the risk of damage. This lock bolt has a right-hand thread, so turn it CCW to loosen it. You can slide a "cheater-pipe" over it, but be careful not to split the bolt in the process. If you cannot remove this bolt without risk of splitting it or other damage, leave it alone until you have the right tool. Do not use too much force or you are in the market for a new hub. Attempt this only if you are willing to take the risk.

Check this out: try to use a T55 6 point star tip usually used for automotive brake systems..... it fits perfectly inside the inner spindle assembly.... this is a 100% guaranteed way to not damage any of the inner assembly.
