Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the brass screw, which can lead to stripping of threads or deformation of the material.Utilize a torque wrench and adhere to the manufacturer's specified torque values for brass fasteners.
Using the wrong size wrench, leading to cam-out and damage to the hex head.Always select a wrench that precisely fits the 32mm head width to ensure secure grip and efficient torque transfer.

Common Applications

  • Marine hardware and fittings
  • Electrical grounding and connections
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid excessive force during installation.
  • Not recommended for structural load-bearing applications where high tensile strength is paramount.
