Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the brass screw, leading to thread stripping or deformation of the mating material.Utilize a torque wrench and adhere to the recommended torque values for the specific application and mating materials to prevent damage.
Using the wrong size wrench on the 9mm hex head, causing cam-out and potential damage to the fastener head.Ensure the wrench or socket size precisely matches the 9mm hex head to guarantee a secure grip and efficient torque application.

Common Applications

  • Marine hardware and fittings
