Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the brass screw, which can lead to thread stripping or deformation.Use a torque wrench set to the manufacturer's recommended specification for M5 brass threads, or tighten until snug and then an additional quarter turn.
Using the wrong size wrench, leading to cam-out and potential damage to the hex head.Ensure a 22mm wrench or socket is used, providing a firm and secure grip on the hex head.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and busbars
  • Decorative and architectural fixtures
  • Low-voltage applications requiring non-magnetic properties

⚠️ Engineering Warnings

  • Brass is softer than steel; avoid excessive force during installation to prevent thread damage or head stripping.
  • While corrosion-resistant, brass can react with certain chemicals; verify compatibility before use in aggressive environments.
