Customer Reviews (4.6 / 5 · 5 reviews)

Lily S. ★★★★★

The low viscosity really makes it easy to wick into tight threads, and even after a day in the garage, I couldn’t budge the bolt I put it on. This stuff absolutely locks everything down, just as advertised for permanent fastening.

Ava ★★★★★

Used this on a stubborn exhaust manifold bolt that kept vibrating loose, and it hasn't budged since. The low viscosity made it easy to apply even on that tight, vertical spot.

Adam ★★★★★

My old bolt on the lawnmower kept backing out but after cleaning it and using this, it hasn't budged at all. The high-strength formula is perfect for a permanent fix and the low viscosity really lets it seep into the threads.
