Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during tightening, leading to thread stripping or fastener fatigue.Always adhere to the manufacturer's recommended torque specifications for the specific application and mating components.
Failure to properly clean mating threads, which can lead to inconsistent torque readings and compromised joint integrity.Thoroughly inspect and clean both the screw threads and the receiving threads before assembly.

Common Applications

  • Aerospace structural components
  • High-performance automotive assemblies
  • Marine hardware and fittings
