Installation Procedure

1. Clean both the bolt threads and the mating tapped hole or nut to remove any debris or lubricant that could affect torque. 2. Apply the appropriate lubricant or anti-seize compound to the threads if specified by the application or design. 3. Thread the cap screw into the mating component by hand for at least two full turns to ensure proper engagement and prevent cross-threading. 4. Using a calibrated torque wrench set to the design specification, tighten the cap screw to the required torque value. Ensure the wrench is applied squarely to the head.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading the screw during initial insertion.Always start threading the screw by hand for several turns to confirm proper thread alignment before using any tools.
Over-tightening or under-tightening the fastener, leading to joint failure or loosening.Utilize a calibrated torque wrench and adhere strictly to the torque specifications outlined in the design documentation.
Using a screw of incorrect length or diameter for the application.Verify the required M22 x 136mm dimensions against the design drawings and material specifications before installation.

Common Applications

  • Heavy machinery assembly
  • Structural steel connections
  • Automotive powertrain components
  • Industrial equipment mounting

⚠️ Engineering Warnings

  • Ensure proper torque is applied to prevent fatigue failure or loosening of the joint.
  • Use appropriate personal protective equipment (PPE) during installation, including safety glasses and gloves.
  • Verify material compatibility between the cap screw and mating components to prevent galvanic corrosion or material degradation.
