Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect thread size for nuts and washers.Always verify that the nuts and washers match the 1/2"-13 thread size of the U-bolt for a secure and effective connection.
Over-tightening the U-bolt, potentially deforming the pipe or support.Apply even pressure and tighten until the U-bolt is snug and the pipe is held securely, but avoid excessive force that could damage components.

Common Applications

  • Marine hardware and rigging
  • Chemical processing pipelines
  • Plumbing and conduit support in corrosive environments

⚠️ Engineering Warnings

  • Ensure material compatibility with surrounding chemicals or environments to maintain corrosion resistance.
  • Verify load-bearing capacity of the U-bolt and support structure for the intended application.
