Long Tangent U-Bolts

Fig 137 U-Bolts Supplier

The Dale Company is a leading manufacturer of long tangent U-Bolts and Fig 137 U-Bolts for industrial applications. We offer standard size and custom long tangent U-bolts at competitive prices, with quick turnaround and same-day shipping for many products.

Long tangent U-bolts Fig 137 have two threaded legs extending from a u-shaped base. The longer legs are used to mount pipe to structural material or thick flanges. The longer thread allows the bolt to be tightened against the pipe diameter, or leave a gap between the pipe and bolt if required.  The bolts are specified by thread diameter and pipe diameter to provide the length and threading required for a secure join. Our Pro-Coat U-Bolts™ offer a corrosion-resistant, low friction bolt that protects the pipe coating and performs well in harsh environments.

Stock bolts have a minimum purchase of $25.

Custom Long Tangent U-Bolt Finishes

Long tangent U-bolts feature two threaded legs extending from a U-shaped base. The extended legs are designed to secure pipes to structural materials or thick flanges. The longer threads allow for precise tightening against the pipe diameter or, if necessary, creating a gap between the pipe and bolt. These bolts are specified based on thread diameter and pipe diameter to ensure the correct length and threading for a secure connection. Our Pro-Coat U-Bolts™ provide a corrosion-resistant, low-friction solution that protects the pipe coating and performs reliably in demanding environments.

Materials

We offer standard sizes for ¼” to 36” pipe, as well as custom sizes and threading to meet your specific application requirements. Materials and finishes available for The Dale Company’s long tangent U-bolts include:

  • Long Tangent U-Bolts Fig. 137Zinc-plated steel
  • 304 and 316 stainless steel
  • Teflon® Blue
  • Plain finish
  • Hot dipped galvanized
  • Hot dipped galvanized Pro-Coat™
  • SermaGard®
