Shook 47158 Fastening System Hanger 1/4-20 Tpi 3/8 in Rod 100/BX

Product Description

The SHOOK MANUFACTURED PRODUCTS 47158 is a vertical-mount fastening system hanger designed to secure threaded rod to structural members in mechanical, electrical, and plumbing installations. The hanger ships in a box of 100 units and pairs a 1/4-20 TPI hex-head screw with a 3/8-inch rod connection point. Constructed from steel, the 47158 provides reliable load-bearing support in suspended piping, conduit, and ductwork applications. Licensed tradespeople in HVAC, plumbing, and electrical disciplines rely on this type of hardware to meet code-required support spacing for overhead systems.

This hanger is suited for residential and commercial installations where 3/8-inch threaded rod is used to suspend mechanical systems from overhead structure. Typical applications include supporting HVAC duct runs, copper or PVC piping, EMT conduit, and similar trade systems that require a fixed vertical attachment point. The hex-head screw allows engagement with standard wrenches and nut drivers during installation, and the vertical-mount design keeps alignment consistent along the rod assembly. Bulk packaging of 100 units per box reduces restocking interruptions on larger jobs.

Key Features

• Steel construction for durable load support in suspended system applications
• 1/4-20 TPI hex-head screw for engagement with standard wrenches or nut drivers
• Compatible with 3/8-inch threaded rod, a common size in mechanical trade hangers
• Vertical-mount orientation maintains consistent rod alignment
• 1-inch screw length suits typical structural attachment depths
• 100 units per box for efficient stocking on multi-point suspension jobs

Compatibility

Designed as an OEM-style replacement and general-use fastening component for suspended mechanical systems utilizing 3/8-inch threaded rod and 1/4-20 TPI screw attachment.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or electricians depending on the suspended system. De-energize or depressurize any associated system before modifying support hardware. Use a properly sized wrench or nut driver on the hex-head screw and tighten to the structural member per project specifications and applicable codes such as the IFGC, IPC, or NEC depending on the application. Do not over-drive the screw into materials that may not support the intended load without appropriate anchors.
