Installation Procedure

1. Clean the threaded hole and the screw threads to remove any debris or contaminants. 2. Apply a suitable thread lubricant or anti-seize compound if required by the application. 3. Insert the cap screw into the designated hole and engage the threads by hand to prevent cross-threading. 4. Tighten the cap screw using an appropriate hex socket or wrench to the specified torque value, ensuring a secure and consistent connection.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading due to improper initial engagement.Always start engaging the threads by hand to ensure proper alignment before applying any torque.
Over-tightening, leading to thread stripping or material deformation.Utilize a calibrated torque wrench and adhere to the recommended torque specifications for the specific application and materials being joined.
Using standard carbon steel fasteners in corrosive environments.Always select 304 stainless steel or a comparable corrosion-resistant material for applications exposed to moisture, chemicals, or saltwater.

Common Applications

  • Structural steel connections
  • Heavy machinery assembly
  • Marine and offshore equipment
  • Chemical processing plants
