Gibraltar 40302G Equal Double Threaded Stud 1/4-20 2in Alloy Steel

Product Description

The GIBRALTAR 40302G is an equal double threaded stud with a 1/4-20 thread size and an overall length of 2 inches. This fastener features threads on both ends of equal length, allowing it to anchor into one component while accepting a nut on the opposite end. Constructed from alloy steel with a black oxide finish, it carries a Material Grade 5 rating and a Thread Fit Class 50 designation. The black oxide treatment provides moderate corrosion resistance and reduces light reflection. It is used in mechanical assemblies, equipment mounting, and structural connections by electricians, HVAC technicians, plumbers, and general trade professionals wherever a stud-type fastener is required.

This stud is suited for light-to-medium duty fastening applications in residential and commercial trade work. Its 1/4-20 unified coarse thread is one of the most common thread standards in North American hardware, making it compatible with a wide range of nuts, couplings, and tapped components. The equal thread configuration makes it interchangeable end-to-end during installation, which simplifies assembly. It is appropriate for use in panel mounting, equipment frames, terminal blocks, and similar mechanical connections across HVAC, electrical, and plumbing service work.

Key Features

• Equal double threaded design — identical threads on both ends for versatile installation
• 1/4-20 unified coarse thread — one of the most widely used thread standards in trade applications
• 2 inch overall length for compact fastening requirements
• Alloy steel construction with Material Grade 5 rating for reliable mechanical strength
• Black oxide finish for moderate corrosion resistance and reduced surface glare
• Thread Fit Class 50 for consistent fit with standard 1/4-20 hardware

Compatibility

Designed as a standard 1/4-20 threaded stud for use with any component, nut, or tapped hole conforming to the 1/4-20 unified coarse thread standard.

Installation Notes

Installation is performed by threading one end of the stud into a tapped hole or coupling, then securing the assembly with a nut on the exposed end. Use an appropriate stud driver or locking nut method to drive the stud without damaging the threads. Ensure the mating tapped hole or component is clean and free of debris before installation. Always de-energize equipment and follow applicable NEC or equipment manufacturer guidelines before working on electrical enclosures or panels.
