Gibraltar 40977G Double Threaded Stud 3/4-10 6 in

Product Description

The GIBRALTAR 40977G is an equal double threaded stud with a 3/4-10 thread size and a 6-inch overall length. This stud is machined from 303-grade stainless steel and finished in black oxide, giving it solid corrosion resistance and a dark, low-reflectance surface. The equal style means both threaded ends are the same length, making it suited for symmetrical fastening applications. Thread fit is Class 50. Weighing 1 pound, this is a heavy-duty fastener intended for structural, mechanical, and industrial assemblies where a permanent or semi-permanent bolt-type connection is required.

This double threaded stud is used in industrial, mechanical, and trade applications where two components must be joined at a fixed centerpoint without a bolt head. Common install scenarios include equipment mounting, pump and motor flange connections, and fabrication work in HVAC, plumbing, and general mechanical trades. The 303 stainless construction makes it appropriate for environments with moderate moisture or chemical exposure. Installed by machinists, pipefitters, millwrights, and general mechanical contractors.

Key Features

• Equal double threaded configuration with identical thread length on both ends
• 3/4-10 UNC thread size for high load-bearing fastening
• 303-grade stainless steel construction for corrosion resistance
• Black oxide finish reduces surface reflectance and provides mild additional corrosion protection
• Class 50 thread fit for consistent, reliable engagement
• 6-inch overall length suits deep flange and through-bolt applications

Compatibility

Designed as a standard equal double threaded stud for industrial and mechanical fastening applications requiring a 3/4-10 UNC thread and 6-inch overall length.

Installation Notes

Installation is performed by qualified machinists, pipefitters, or mechanical contractors. Shut down and de-energize or depressurize the equipment assembly before installing or removing studs. Use the appropriate stud driver or two-nut method to thread the stud into the tapped hole without applying torque to the stud body itself. Follow applicable mechanical codes and equipment manufacturer guidance for fastener preload and assembly procedures.
