Value Collection C32817 Round U-bolt 3/8-16 Unc 1-1/2 in Pipe

Product Description

The VALUE COLLECTION C32817 is a round U-bolt designed to secure 1-1/2 inch pipe in mechanical, plumbing, and HVAC piping installations. Manufactured from C1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt features a 3/8-16 UNC thread with a 1-1/2 inch thread length. The package includes two nuts, making it ready for immediate installation without sourcing separate hardware. Each order ships in a pack of five units. Plumbers, pipefitters, and HVAC technicians use this style of fastener when anchoring pipe runs to structural members, hangers, or unistrut-style channel without a mount plate. The round shape conforms to standard pipe OD profiles for consistent clamping force.

This U-bolt is suited for residential and light commercial pipe support applications where a clean, round clamp profile is required. Typical installations include securing copper, steel, or plastic pipe runs along joists, beams, or support strut. The zinc plating offers adequate protection for indoor and sheltered outdoor environments. The without-mount-plate configuration allows the U-bolt to thread directly through a drilled hole or paired channel nut, giving installers flexibility in mounting approach. It is commonly used in mechanical rooms, utility spaces, and overhead piping systems.

Key Features

• Round U-bolt profile sized for 1-1/2 inch pipe outside diameter
• 3/8-16 UNC thread standard with 1-1/2 inch thread length for positive engagement
• C1010 steel construction for reliable tensile strength in pipe support applications
• Zinc-plated finish provides corrosion protection in indoor and sheltered environments
• Includes two nuts per U-bolt — no additional hardware required
• Sold in a pack of five units for common multi-point pipe support jobs

Compatibility

Designed for use with 1-1/2 inch nominal pipe in standard pipe support and anchoring applications. Compatible with installations following inch measurement standards where a 3/8-16 UNC threaded U-bolt without a mount plate is specified.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable mechanical and plumbing codes such as the IPC or IFGC. Before installing or adjusting pipe supports on active systems, isolate and depressurize the line as required. Ensure the U-bolt is seated squarely around the pipe before tightening the nuts evenly to avoid uneven clamping. Do not over-tighten on plastic or soft-wall pipe, which can deform under excessive clamping force.
