Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size socket, which can strip the hex head.Always use a correctly sized socket that fits snugly onto the hex head.
Over-tightening the screw, leading to thread damage or premature failure.Adhere to specified torque values for the application to prevent over-stressing the fastener and mating components.

Common Applications

  • Heavy construction and structural bolting
  • Marine and offshore equipment fastening
  • Industrial machinery and equipment assembly

⚠️ Engineering Warnings

  • Ensure the mating components are compatible with 304 stainless steel to avoid galvanic corrosion.
  • Always use appropriate safety equipment, including gloves and eye protection, during installation.
