Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during tightening, leading to thread stripping or fastener failure.Always adhere to recommended torque specifications for the application and material being joined.
Not cleaning mating surfaces, which can lead to uneven load distribution and potential loosening.Thoroughly clean both the screw threads and the receiving threads or nut before assembly.

Common Applications

  • Structural steel connections
  • Machinery and equipment assembly
  • Marine and offshore installations

⚠️ Engineering Warnings

  • Always use appropriate personal protective equipment (PPE) during installation.
  • Ensure compatibility of 304 stainless steel with the intended environment to prevent galvanic corrosion if dissimilar metals are used in conjunction.
