Gibraltar 40904G Double Threaded Stud 3/4-10 4.5in Alloy Steel

Product Description

The GIBRALTAR 40904G is an equal double threaded stud with a 3/4-10 thread size and an overall length of 4.5 inches. Manufactured from alloy steel with a black oxide finish, this stud is built for high-stress mechanical fastening applications where both ends require threaded engagement. The material grade 5 construction and Class 50 thread fit provide consistent clamping force and dimensional accuracy. The flat feature aids in installation with standard wrenching tools. Plumbers, pipefitters, electricians, and mechanical contractors use double threaded studs like this for equipment mounting, flange assemblies, and structural fastening tasks requiring a fixed, non-removable threaded element.

This stud is suited for residential and commercial mechanical installations where a reliable, corrosion-resistant fastener is required. The black oxide finish provides moderate corrosion resistance while reducing light reflection in finished assemblies. Equal thread configuration means both ends share the same 3/4-10 thread spec, simplifying nut selection and torque distribution. Typical applications include equipment base mounting, pump flanges, compressor frames, and general mechanical assemblies encountered in HVAC, plumbing, and industrial service work.

Key Features

• Equal double threaded configuration with matching 3/4-10 threads on both ends
• Alloy steel construction with material grade 5 for high tensile strength
• Black oxide finish for moderate corrosion resistance and reduced surface glare
• Class 50 thread fit for consistent dimensional accuracy and reliable engagement
• Flat feature accommodates standard wrenching for installation and removal
• 4.5 inch overall length suits a range of flange depths and equipment mounting configurations

Compatibility

Designed as a general-purpose equal double threaded stud for mechanical fastening applications requiring a 3/4-10 thread size and 4.5 inch overall length.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, HVAC mechanics, or general mechanical contractors. De-energize and isolate all connected equipment before servicing fasteners in pressurized or energized assemblies. Use properly rated wrenches and follow the equipment manufacturer torque guidance for the mating assembly. Verify thread engagement depth on both ends before applying load to the stud.
