Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the cap screw, leading to thread stripping or fastener fracture.Utilize a calibrated torque wrench and adhere to recommended torque specifications for the specific application and material.
Using the wrong size or type of tool for tightening, potentially damaging the hex head.Always use a correctly sized hex socket or wrench that fits snugly on the 17mm head to prevent cam-out and stripping.

Common Applications

  • Heavy machinery construction
  • Structural steel fabrication
  • Automotive assembly
  • Industrial equipment mounting
