Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to head damage or improper torque.Utilize a correctly sized wrench (14mm) to ensure a snug fit and efficient torque application.
Overtightening, which can strip threads or compromise the fastener's integrity.Adhere to the specified torque values for the application to prevent damage and ensure reliable performance.
Using in a highly corrosive environment without verifying 316 stainless steel suitability.Confirm that the specific corrosive agents and concentrations in the environment are within the acceptable limits for 316 stainless steel.

Common Applications

  • Marine and offshore equipment
  • Chemical processing plants
  • Food and beverage production machinery
  • Pharmaceutical manufacturing equipment
  • Coastal infrastructure

⚠️ Engineering Warnings

  • Always use appropriate personal protective equipment (PPE) during installation.
  • Ensure the fastener is compatible with the mating materials to prevent galvanic corrosion.
  • Do not exceed the recommended tensile strength for the fastener or the assembled components.
