Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or fastener fracture.Always use a calibrated torque wrench and adhere to recommended torque values for the specific application and mating component.
Using incorrect thread engagement or mating hardware.Verify that the screw's thread pitch and diameter are compatible with the nut or tapped hole, and ensure sufficient thread engagement for the load.

Common Applications

  • Structural steel fabrication and assembly
  • Heavy machinery and equipment mounting
  • Marine and offshore equipment installations
  • Chemical processing plant construction

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) during installation.
  • Ensure proper thread engagement to achieve full load-bearing capacity. Do not use if threads are damaged.
