Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to head stripping.Always use the correct size wrench (19mm) that fits snugly onto the hex head to prevent damage during installation.
Over-tightening, causing thread damage or bolt failure.Utilize a calibrated torque wrench and adhere to the specified torque values for the M17 thread and application to ensure proper clamping force without compromising fastener integrity.
Not considering the corrosive environment for material selection.Select 316 stainless steel for applications involving saltwater, chemicals, or high humidity to ensure long-term corrosion resistance and performance.

Common Applications

  • Marine hardware and deck fittings
  • Chemical processing equipment
  • Food and beverage processing machinery
  • Offshore structures
  • Medical equipment

⚠️ Engineering Warnings

  • 316 stainless steel is susceptible to crevice corrosion in stagnant, low-oxygen environments; inspect regularly.
  • Galvanic corrosion can occur if dissimilar metals are in direct contact; use appropriate isolation methods if necessary.
