Gibraltar ST4-50-G Double Threaded Stud 3/4-10 5 in

Product Description

The GIBRALTAR ST4-50-G is an equal double threaded stud designed for fastening applications that require threaded engagement on both ends. The stud features a 3/4-10 Unified National Coarse (UNC) thread with left and right hand thread direction and an overall length of 5 inches. Machined from 1117 grade carbon steel with a black oxide finish, it provides moderate corrosion resistance and surface hardness suited for industrial and mechanical assembly work. Weighing 0.51 pounds, this stud is a standard-duty fastener used by millwrights, pipefitters, and general mechanical contractors in structural and equipment mounting applications.

This double threaded stud is used in applications where a bolt cannot pass completely through an assembly, or where two separate components must be joined with threaded engagement on both faces. Typical install scenarios include equipment base mounting, flange connections, and machinery assembly in industrial, HVAC mechanical room, and plumbing equipment settings. The equal thread configuration means both ends share the same 3/4-10 thread spec, simplifying hardware selection when mating nuts or tapped holes are required on both sides.

Key Features

• 3/4-10 UNC thread on both ends for equal double-threaded engagement
• Overall length of 5 inches to accommodate a range of assembly stack-ups
• 1117 grade carbon steel construction for reliable strength in mechanical fastening
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Left and right hand thread direction compatibility

Compatibility

Designed as an OEM-style replacement or standard-duty fastener for industrial and mechanical assemblies requiring a 3/4-10 UNC equal double threaded stud with a 5 inch overall length.

Installation Notes

Installation is typically performed by millwrights, pipefitters, or mechanical contractors using standard 3/4-inch drive or wrench tooling. Power down and de-energize all connected equipment before beginning fastener replacement or assembly work. Verify that mating tapped holes or nuts match the 3/4-10 UNC thread spec and that the installation torque conforms to the applicable engineering specification for the assembly. Inspect stud threads for damage before installation and do not force a stud into a misaligned or cross-threaded hole.
