Gibraltar 41117G Equal Double Threaded Stud 1-8 Thread 18 in

Product Description

The GIBRALTAR 41117G is an equal double threaded stud designed for heavy-duty fastening applications where both ends of the stud carry identical thread profiles. Manufactured from alloy steel with a black oxide finish, this stud measures 18 inches overall length and is threaded to a 1-8 UNC specification. The black oxide coating provides moderate corrosion resistance and reduces light reflection on exposed hardware. With a Material Grade 5 rating and Thread Fit Class 50, it is suited for structural and mechanical assemblies requiring reliable clamp load and thread engagement. Trades handling HVAC equipment frames, mechanical supports, and structural fastening will find this stud a standard workhorse component.

This stud is used in residential and commercial settings wherever a through-bolt or double-end fastener is needed to join components from both sides. Typical applications include equipment mounting frames, pipe supports, unistrut assemblies, and structural connections. The equal thread configuration means both ends accept the same nut or coupling, simplifying hardware selection on the job. The 18-inch length accommodates thicker panel stacks, insulated sections, or extended reach mounting situations. Electricians, HVAC technicians, pipefitters, and general mechanical contractors commonly stock this size for field fabrication and equipment installation work.

Key Features

• Equal double threaded ends — both ends carry identical 1-8 UNC threads for symmetrical fastening
• Alloy steel construction with Material Grade 5 rating for high tensile strength applications
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• 18-inch overall length accommodates deep stack assemblies and extended reach installations
• Thread Fit Class 50 for consistent engagement with standard Grade 5 compatible nuts and couplings
• Flat wrench flats included for torque application during installation

Compatibility

Designed as a standard 1-8 UNC equal double threaded stud for use with compatible Grade 5 hex nuts, coupling nuts, and threaded inserts in mechanical, structural, and equipment mounting assemblies.

Installation Notes

Installation is typically performed by millwrights, pipefitters, HVAC technicians, or general mechanical contractors using standard open-end or socket wrenches. Ensure all equipment or structural assemblies are de-energized and depressurized before beginning fastener work. Apply thread lubricant or anti-seize compound as required by the application environment to prevent galling on alloy steel threads. Follow applicable structural or mechanical codes for fastener torque requirements based on joint design.
