Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or damaged tool for tightening, leading to stripped head or improper torque application.Always use a correctly sized, high-quality hex wrench or socket. Inspect tools for wear before use.
Applying excessive torque, which can lead to thread stripping, bolt fracture, or deformation of the mating components.Refer to engineering specifications for correct torque values. Utilize a torque wrench for precise control.
Not verifying thread compatibility with the mating component, resulting in cross-threading or inability to assemble.Confirm that the M6 thread pitch and form of the screw match the tapped hole or nut precisely.

Common Applications

  • Marine hardware and offshore structures
  • Chemical processing equipment
  • Food and beverage processing machinery
  • Pharmaceutical manufacturing

⚠️ Engineering Warnings

  • Ensure compatibility with mating materials to prevent galvanic corrosion.
  • Handle with care to avoid damage to threads or the fastener head.
