Empire 55B50040 Steel Hanger Bolt 1/2-13 4 in

Product Description

The EMPIRE 55B50040 is a steel hanger bolt designed for structural fastening applications where a wood-screw end drives into a substrate and a machine-thread end accepts a nut or fitting. With a 1/2-13 thread size and an overall length of 4 inches, this fastener is suited for medium-to-heavy-duty anchoring tasks in mechanical and construction trades. The uncoated steel finish makes it appropriate for interior use or applications where a secondary coating will be applied on-site. Installers working in HVAC equipment mounting, pipe hangers, and general mechanical support applications will find this a standard utility fastener.

This hanger bolt is used in residential and light commercial installations where equipment, pipe, or ductwork support systems require a threaded stud anchored into wood framing, blocking, or structural members. It is a common component in overhead support assemblies for piping, conduit, and mechanical equipment pads. The 1/2-13 machine thread end accepts standard hex nuts and washers for secure, adjustable load points.

Key Features

• 1/2-13 unified coarse machine thread for compatibility with standard nuts and hardware
• 4 inches overall length suits a range of mounting depths and substrate thicknesses
• Uncoated steel construction for interior structural fastening applications
• Dual-end design: wood-screw drive end and machine-thread load end in one fastener
• Sold individually, allowing single-unit procurement for service and repair needs

Compatibility

Designed as a general-purpose 1/2-13 hanger bolt for use in standard wood-to-machine-thread fastening applications across mechanical, plumbing, and HVAC support assemblies.

Installation Notes

Hanger bolts are typically installed by licensed HVAC technicians, plumbers, and general mechanical contractors. Drive the wood-screw end into pre-drilled or self-started holes in wood framing using two jam nuts threaded onto the machine end as a driving aid. De-energize all equipment and relieve system pressure before working on any suspended mechanical assembly. Follow applicable local building codes and manufacturer load ratings when sizing support hardware for overhead installations.
