Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or fastener fracture.Utilize a calibrated torque wrench and adhere strictly to recommended torque specifications for the fastener and application.
Using the wrong tool size, resulting in damaged hex head and improper torque application.Always use a correctly sized, high-quality hex socket or wrench that fits snugly to the screw head.
Failing to inspect threads for damage or contamination before installation.Visually inspect both the screw threads and the internal threads of the mating component for any signs of damage, dirt, or foreign material.

Common Applications

  • Marine and offshore equipment assembly
  • Chemical processing plant construction
  • Food and beverage processing machinery
  • Structural steel connections in corrosive atmospheres
  • High-pressure fluid systems

⚠️ Engineering Warnings

  • Ensure compatibility with mating threads and materials to prevent galvanic corrosion.
  • Do not exceed the maximum recommended torque values to avoid fastener failure.
