Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or fastener breakage.Consult torque charts for the specific application and material to determine the correct tightening torque.
Using a socket that does not fully engage the hex head, causing cam-out and potential damage to the fastener.Utilize a correctly sized and high-quality socket that fits snugly on the hex head.

Common Applications

  • Structural steel connections
  • Marine hardware and equipment
  • Chemical processing equipment assembly

⚠️ Engineering Warnings

  • Ensure compatibility with mating components to prevent galvanic corrosion.
