Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or fastener fatigue.Always adhere to the manufacturer's recommended torque specifications for the screw and the application.
Using the wrong tool size for the hex head, causing damage to the fastener head.Employ the correct size hex socket or wrench that fits snugly to prevent slippage and damage.
Installing in a corrosive environment without considering the specific grade of stainless steel's limitations.Verify that 304 stainless steel is suitable for the specific corrosive agents present in the operating environment.

Common Applications

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

⚠️ Engineering Warnings

  • Ensure compatibility of mating materials and thread pitch before installation.
  • Always use appropriate safety gear, including eye protection, during installation.
