Gibraltar 40378G Double Threaded Stud 1/4-20 5 in Oal

Product Description

The GIBRALTAR 40378G is an equal double threaded stud with a 1/4-20 thread size and a 5-inch overall length. This stud is machined from 303 stainless steel with a black oxide finish, making it well-suited for fastening applications that require corrosion resistance and a clean appearance. The equal thread configuration means both ends share the same 1/4-20 thread, allowing it to connect two mating components with consistent thread engagement on each side. It carries a Thread Fit Class 50 designation, indicating a standard fit tolerance appropriate for general mechanical assemblies. Electricians, HVAC technicians, and mechanical contractors use studs like this when mounting hardware, panels, or equipment brackets in trade installations.

This double threaded stud is appropriate for use in residential and commercial mechanical systems where a reliable, reusable threaded fastener is needed. Common applications include equipment mounting, control panel assembly, and structural hardware connections. The black oxide finish on stainless steel provides a low-reflectance surface while maintaining the corrosion-resistance properties of the 303 stainless base material. It is sold individually, with a minimum order quantity of 2 units.

Key Features

• Equal double threaded configuration with 1/4-20 thread on both ends
• 303 stainless steel construction for corrosion resistance in demanding environments
• Black oxide finish for reduced reflectance and surface protection
• 5-inch overall length suits a wide range of mounting depths
• Thread Fit Class 50 for standard mechanical assembly tolerance
• No flat on the stud body — thread-only profile for compact installations

Compatibility

Designed as a general-purpose equal double threaded stud for mechanical, electrical, and HVAC assemblies requiring a 1/4-20 threaded fastener with a 5-inch overall length.

Installation Notes

This stud is typically installed by hand-threading one end into a tapped hole or coupling nut, then securing the assembly with the opposite end. Always de-energize and lock out any electrical or mechanical system before fastener work on live equipment. Use appropriate thread-locking compound or hardware per the equipment manufacturer's instructions. Verify thread engagement depth meets the structural requirements of the application before final assembly.
