Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or component damage due to brass's lower tensile strength compared to steel.Always adhere to the recommended torque specifications for M22 brass fasteners and use calibrated torque wrenches.
Improper cleaning of mating threads, which can lead to galling or reduced clamping force.Ensure both the screw threads and the mating threads are clean and free of debris or contaminants before assembly.

Common Applications

  • Marine and offshore equipment
  • Electrical and chemical processing industries
  • Environments requiring non-sparking fasteners

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid over-tightening to prevent thread damage.
  • While corrosion-resistant, brass may react with certain aggressive chemicals; verify material compatibility for specific applications.
