U Bolts Black Oxide with Two Nuts 5/16 X 3 X 3 11/16 — a durable mounting solution engineered from steel with a protective black oxide finish. This package includes two nuts for fast, secure installation on round objects.

Designed for versatility, these U-bolts are ideal for securing pipes, conduits, exhaust lines, or other cylindrical components to a flat surface in automotive, plumbing, or industrial settings. The black oxide finish provides a clean, low-profile appearance with added corrosion resistance suitable for indoor or sheltered outdoor use.

  • Material: steel with a black oxide finish
  • Includes: two nuts for immediate mounting
  • Size: 5/16 in diameter, with dimensions described as 3 x 3 11/16 in
  • Applications: securing round objects to rails, brackets, or frames in automotive, HVAC, and construction projects

To ensure a secure fit, install with compatible hardware and tighten nuts to the recommended torque for your application. Store in a dry place to maintain finish and prevent rust.
