Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size socket, leading to stripped hex head corners.Always use a correctly sized socket that fits snugly on all hex facets.
Over-torquing the fastener, causing thread damage or component deformation.Adhere to recommended torque specifications for the application and material being fastened.
Not cleaning mating threads, resulting in increased friction and inaccurate torque readings.Thoroughly clean both the screw threads and the receiving threads before assembly.

Common Applications

  • Heavy machinery assembly
  • Structural steel connections
  • Automotive chassis components

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) such as safety glasses and gloves.
  • Ensure the fastener's tensile strength is adequate for the anticipated load and application environment.
