## Questions & Answers

**Q: If i apply this product on brake bracket-to-steering knuckle bolts will i be able to loosen those bolts just w/huge breaker bar, without heat?**
A: Sorry, I meant to type primer SF 7649 or SF 7471.

Loctite 277 is a high strength threadlocker that requires primer SF 7649 or 7411 when it's applied on 2 plated metals, 2 low energy surfaces, or 2 non-active metal surfaces.  If one of the parts is active, the primer is not required.

After the product cures, applying head and removing while the assembly is still hot, is the best/safest way to disassemble without stripping the threads.  You could try removing with a hand tool first, but the resistance is too much, heat the head of the screw to 450F to disassemble.
