Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an improperly sized wrench, leading to stripped hex heads.Always use a correctly sized metric wrench that fits snugly to apply torque effectively and prevent damage to the fastener head.
Over-tightening or under-tightening, compromising joint integrity.Utilize a calibrated torque wrench to achieve the recommended torque specifications for the specific application and material being joined.

Common Applications

  • Heavy Machinery Assembly
  • Structural Steel Connections
  • Industrial Equipment Manufacturing

⚠️ Engineering Warnings

  • Ensure proper thread engagement to avoid cross-threading, which can damage both the screw and the mating component.
  • Use appropriate personal protective equipment (PPE) such as safety glasses and gloves during handling and installation.
