Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using undersized or incorrect thread size nuts.Always verify that the nuts and washers are specifically designed for 1/2"-13 UNC threads to ensure a proper and secure connection.
Over-tightening the U-bolt, deforming the pipe or support.Tighten nuts until snug and secure, checking for pipe deformation or excessive stress on the support structure. Evenly tighten in alternating steps.

Common Applications

  • Pipe Support and Clamping
  • Conduit and Cable Securing
  • Structural Beam Attachment

⚠️ Engineering Warnings

  • Ensure compatibility with pipe material and operating temperature.
  • Do not exceed the rated load capacity of the U-bolt and its associated hardware.
