Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the cap screw, leading to thread stripping or bolt fracture.Always adhere to the specified torque values for the application, utilizing a calibrated torque wrench for accuracy.
Using the wrong size wrench on the hex head, causing damage to the head or slippage.Ensure the wrench fits snugly and completely engages all flats of the hex head to prevent damage and ensure effective tightening.

Common Applications

  • Heavy machinery assembly
  • Structural steel connections
  • Automotive manufacturing and repair
  • Industrial equipment maintenance

⚠️ Engineering Warnings

  • Ensure the mating threads are clean and free of debris to achieve proper engagement and prevent damage.
  • For critical applications, consider using thread-locking compounds to prevent loosening due to vibration.
