Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized wrench, leading to cam-out and potential damage to the fastener head.Always use a wrench or socket that precisely fits the 17mm hex head to ensure full engagement and prevent slippage.
Over-tightening, which can strip threads or compromise the structural integrity of the fastener or mating component.Employ a calibrated torque wrench and adhere to recommended torque specifications for M23 carbon steel fasteners to achieve optimal clamping force without overstressing the components.

Common Applications

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

⚠️ Engineering Warnings

  • Ensure thread compatibility with the mating component to prevent cross-threading or galling.
  • Use appropriate personal protective equipment (PPE) during installation, including safety glasses and gloves.
