Gibraltar 40804G Double Threaded Stud 5/8-11 3 Inch Alloy Steel

Product Description

The GIBRALTAR 40804G is an equal double threaded stud with a 5/8-11 thread size and an overall length of 3 inches. Made from alloy steel with a black oxide finish, this stud is built for strength and corrosion resistance in demanding fastener applications. The Grade 5 material rating and Class 50 thread fit class make it suitable for structural and mechanical assemblies where consistent clamping force and thread engagement are required. It features a flat, allowing for wrench engagement during installation. Machinists, millwrights, and maintenance technicians commonly use this style of stud in equipment assembly, repair, and fabrication work.

Equal double threaded studs are used in applications where both ends must engage threaded components simultaneously, such as mounting flanges, securing covers, or assembling mechanical equipment. This stud is appropriate for industrial maintenance, general fabrication, and equipment repair scenarios requiring a reliable Grade 5 alloy steel fastener. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision environments.

Key Features

• Equal double threaded design with 5/8-11 thread on both ends for symmetric engagement
• Alloy steel construction with Grade 5 material rating for high tensile strength
• Black oxide finish for mild corrosion resistance and a clean appearance
• Class 50 thread fit for consistent, reliable thread engagement
• Flat included for wrench access during installation or removal
• 3 inch overall length suits a wide range of standard fastener stack-ups

Compatibility

Designed as a standard replacement or new-install fastener for mechanical assemblies, flanged connections, and equipment mounting applications requiring a 5/8-11 thread pattern and 3 inch overall length.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians. Power down and de-energize any equipment before replacing or installing studs in live assemblies. Use a properly sized wrench on the flat to avoid thread damage during installation. Follow applicable industry torque guidelines for Grade 5 5/8-11 fasteners based on the joint design specifications for your application.
