National Hardware N222-182 Zinc U-bolt Model 542

Product Description

The NATIONAL HARDWARE N222-182 is a zinc-finish U-bolt sold as a single unit under model 542. U-bolts are threaded fasteners shaped into a U-profile with two parallel threaded legs and a curved saddle. They are used to secure pipe, conduit, rod, or structural members to a mounting surface. The zinc finish provides a base level of corrosion resistance suitable for general-purpose mechanical and structural fastening applications. This type of hardware is installed by plumbers, electricians, pipefitters, and general contractors in both residential and commercial settings.

The N222-182 U-bolt is appropriate for use in standard pipe support, conduit clamping, and light structural attachment applications. It is sold as a single piece, making it practical for replacement installs or low-quantity repair work. The zinc coating is consistent with typical indoor and sheltered outdoor fastener requirements where moderate environmental exposure is expected.

Key Features

• Zinc finish for general corrosion resistance
• U-bolt profile with two threaded legs for secure clamping
• Sold as a single unit for replacement or repair use
• Model 542 designation for direct cross-reference ordering

Compatibility

Designed as a general-purpose U-bolt suitable for standard pipe support, conduit securing, and structural clamping applications where a zinc-finish threaded fastener is specified.

Installation Notes

U-bolts of this type are installed using standard wrenches or sockets to seat the nuts evenly on both threaded legs. Apply torque in alternating passes across both nuts to ensure even clamping load and avoid distorting the saddle. Consult applicable mechanical, plumbing, or electrical codes such as the NEC or IPC for required pipe and conduit support intervals and fastener ratings before installation.
