Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using lower grade stainless steel in corrosive environments.Always specify 316 stainless steel for marine, chemical, or high-salinity applications to prevent premature corrosion and failure.
Overtightening the screw, leading to thread stripping or material fatigue.Consult engineering drawings or torque charts for the correct tightening torque based on the mating materials and screw size.

Common Applications

  • Marine hardware and fittings
  • Chemical processing equipment
  • Food and beverage machinery
  • Pharmaceutical manufacturing
  • Outdoor structural applications

⚠️ Engineering Warnings

  • Ensure compatibility with mating materials to avoid galvanic corrosion.
  • Apply appropriate lubrication if thread galling is a concern, especially in stainless steel to stainless steel applications.
