Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening, leading to thread stripping or deformation of the brass material.Utilize a torque wrench to adhere to recommended torque values for brass fasteners, preventing excessive stress.
Using the wrong size wrench, resulting in damage to the hex head and difficulty in proper tightening.Always select a wrench or socket that precisely fits the 20mm head width of the screw.

Common Applications

  • Marine hardware and equipment
  • Electrical grounding and connection points
  • Plumbing fixtures and systems
  • Corrosive industrial environments

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; avoid excessive force that could damage threads or the fastener itself.
  • Not recommended for structural load-bearing applications where high tensile strength is critical; consider steel alternatives.
