Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, which can strip the brass threads or deform the component.Adhere to the manufacturer's recommended torque specifications for brass fasteners.
Using the screw in a high-stress structural application where brass's lower tensile strength may be insufficient.Verify the material's suitability for the load requirements; consider steel alloys for higher strength needs.

Common Applications

  • Marine hardware and fittings
  • Chemical processing equipment
  • Electrical connectors and enclosures
  • Non-sparking tool applications

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in certain aggressive environments; verify compatibility.
  • Do not use in applications requiring high tensile strength or significant shear loads.
