Powers Bolt Review
Review by: rngrchad, 2008-04-07
Great Bolt. A lot of folks buy these carbon steel, and then put a stainless steel hanger on them which is something you should not do, as mixing two different metals causes an increased rate in oxidation and rusting. Might I also mention these powers 5 piece bolts have a tendancy to become "spinners" if you aren't really careful about cleaning your bolt hole, or if you are drilling in soft rock. Soft rock applications should use this in a 1/2" size and if you are having problems with "spinners", removing the blue crush-sleeve will help eliminate this common problem, however creating a bolt that will have no "lock" washer effect. So be careful of them loosening if you have removed the blue-crush sleeve.
note: I really think bolting is a bad idea unless you are of the utmost knowledge of the land, mechanics and ownership of the rock with which you are applying these rawls to.
