Gibraltar 41108G Double Threaded Stud 1-8 Thread 6.5 in

Product Description

The GIBRALTAR 41108G is an equal double threaded stud designed for heavy-duty fastening applications where both ends require threaded engagement. Machined from alloy steel with a black oxide finish, this stud provides corrosion resistance and surface hardness suited to demanding mechanical and industrial environments. It carries a Thread Fit Class 50 designation and a material grade of 5, confirming its suitability for structural and high-load assemblies. The 1-8 thread size indicates a 1-inch nominal diameter with 8 threads per inch (UNC series), and the overall length of 6.5 inches accommodates deeper stack assemblies or applications requiring extended thread engagement on both ends. Installation is typically performed by millwrights, pipefitters, or maintenance technicians working on structural connections, machinery mounts, or piping flanges.

This stud is suited for use in industrial, commercial, and trade applications where a removable, double-ended threaded fastener is required. Equal thread configuration means both ends carry the same thread specification, simplifying assembly when identical engagement depth is needed on both sides of a joint. The flat feature on this stud allows for wrench engagement during installation without marring the threads. Typical applications include equipment mounting, flange bolting, and mechanical assemblies requiring a stud-and-nut fastening method on both faces of a component.

Key Features

• Equal double threaded configuration — both ends share the same 1-8 UNC thread specification
• Alloy steel construction with material grade 5 for high-strength, load-bearing service
• Black oxide finish provides mild corrosion resistance and reduces light reflection in service environments
• Thread Fit Class 50 for controlled fit tolerance in precision mechanical assemblies
• Flat feature allows wrench engagement for controlled installation torque without thread damage
• 6.5-inch overall length accommodates thicker substrates or extended engagement requirements

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for mechanical assemblies, flanged connections, and equipment mounts requiring a 1-8 UNC equal double threaded stud with a 6.5-inch overall length.

Installation Notes

Installation is typically performed by licensed millwrights, pipefitters, or qualified maintenance technicians following applicable mechanical and structural codes. De-energize and isolate all equipment before beginning fastener installation or replacement. Use the flat feature with an appropriate wrench to drive the stud without damaging threads. Verify thread engagement depth and joint load requirements against the assembly specification before torquing mating nuts.
