Installation Procedure

1. Select the appropriate mating component with a tapped hole or nut for M18 thread. 2. Insert the cap screw, ensuring threads engage smoothly to prevent cross-threading. 3. Tighten the cap screw using a suitable wrench or socket, applying consistent torque as specified by design requirements, avoiding over-tightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading the screw by forcing it into the mating component.Gently start the screw by hand to ensure proper thread alignment before applying any torque.
Over-tightening the brass screw, which can lead to deformation or stripping of threads.Use a torque wrench to adhere to specified torque values, or tighten until snug and then a quarter turn, depending on application criticality.

Common Applications

  • Electrical Connectors and Busbars
  • Marine Hardware and Fittings
  • Decorative and Architectural Elements
  • Plumbing and Valve Assemblies

⚠️ Engineering Warnings

  • Brass may be susceptible to dezincification in aggressive environments; consult material compatibility charts for specific applications.
  • Avoid use in applications requiring extreme tensile strength or resistance to high impact loads; consider higher-strength alloy steel fasteners for such needs.
