Value Collection C4399 Round U-bolt 5/16-18 Unc 2 in Pipe 5 Pack

Product Description

The VALUE COLLECTION C4399 is a round U-bolt designed to secure 2-inch pipe without a mount plate. Built from C-1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt uses a 5/16-18 UNC thread standard with a 1-1/2 inch thread length. The overall length is 3-1/2 inches and the width measures 2-1/2 inches. Each unit ships with two nuts included. Sold in a pack of 5, this fastener is suited for plumbing, HVAC, and general mechanical applications where reliable pipe support is required. Plumbers, pipefitters, and mechanical contractors are the primary installers.

This U-bolt is used in residential and light commercial installations to clamp and support 2-inch pipe runs. Typical applications include securing copper, steel, or plastic pipe to structural members, strut channel, or equipment frames. The round shape conforms to standard pipe outside diameter, providing consistent contact and load distribution. Without a mount plate, the U-bolt threads directly through a support surface or pairs with a separately sourced plate or strut fitting as needed by the installation.

Key Features

• Round shape fits 2-inch nominal pipe outside diameter
• 5/16-18 UNC thread with 1-1/2 inch thread length for standard nut engagement
• C-1010 steel construction for strength in mechanical pipe support applications

• Includes two nuts per U-bolt — no separate hardware purchase required
• Sold as a pack of 5 units for multi-point installations

Compatibility

Designed as a standard round U-bolt for 2-inch nominal pipe, suitable for use in plumbing, HVAC piping, and general mechanical piping support applications where a 5/16-18 UNC fastener without a mount plate is specified.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or mechanical contractors following applicable IPC and IFGC support spacing requirements for the pipe type and size. Power down or depressurize any active system before repositioning or adding pipe supports. Use appropriately rated hardware and backing structure to meet load requirements. Tighten nuts evenly to avoid distorting the U-bolt legs or crushing the pipe wall.
