Hillman Builders Hardware 320902 Forged Square U-bolt

Product Description

The HILLMAN BUILDERS HARDWARE 320902 is a forged square U-bolt with a 3/8-16 thread size and a 6 x 4 inch body configuration. Forged construction provides greater tensile strength and fatigue resistance compared to standard bent rod U-bolts, making this hardware suitable for demanding clamping and mounting applications. The square bend profile is designed to secure square or rectangular tubing, pipes, or structural members where a round-bend U-bolt would not provide full surface contact. Plumbers, electricians, HVAC installers, and general contractors commonly use square U-bolts for securing pipe runs, conduit, strut channel, and equipment frames.

This U-bolt is applicable across a range of residential and light commercial installation scenarios. It is well suited for securing square tubing to flat surfaces, anchoring piping to structural supports, and mounting equipment to racking or framing. The 3/8-16 thread pitch accommodates standard hex nuts and lock nuts for secure fastening. It is sold as an individual unit and is appropriate for both new construction and retrofit service work.

Key Features

• Forged construction for increased tensile strength and durability over bent-rod alternatives
• Square bend profile designed to match square or rectangular tubing and structural members
• 3/8-16 thread size for compatibility with standard hex nuts and hardware
• 6 x 4 inch body dimensions for precise fit in targeted mounting applications
• Single-unit packaging for exact-quantity procurement on service calls

Compatibility

Designed as an OEM-style replacement and general-purpose forged square U-bolt suitable for pipe support, conduit mounting, and structural clamping applications requiring a 3/8-16 thread and a 6 x 4 inch square-bend profile.

Installation Notes

Installation is performed by the appropriate licensed trade based on the application, including plumbers, HVAC technicians, or electricians. Always de-energize electrical systems or shut off relevant supply lines before securing hardware in live service areas. Use properly rated nuts, washers, and backing plates as required by the application and local code. Do not over-torque the mounting nuts, as over-tightening can deform tubing or compromise thread integrity.
