Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the brass screw, which can lead to thread stripping or deformation.Always adhere to the manufacturer's recommended torque specifications or use a torque wrench for precise tightening.
Using the wrong size wrench, potentially damaging the hex head or the tool.Select a wrench that precisely fits the 32mm head width of the cap screw for optimal engagement and torque transfer.

Common Applications

  • Marine hardware and fittings
  • Architectural and decorative assemblies
  • Electrical connectors and enclosures

⚠️ Engineering Warnings

  • Brass may deform under excessive force; do not overtighten.
