Gibraltar 40307G Equal Double Threaded Stud 1/4-20 4.5 in

Product Description

The GIBRALTAR 40307G is an equal double threaded stud with a 1/4-20 thread size and an overall length of 4.5 inches. This stud is fully threaded on both ends with equal thread engagement, making it suited for through-bolt and double-fastener applications in mechanical assemblies, brackets, and structural connections. Constructed from alloy steel with a black oxide finish, it carries a material grade of 5 and a thread fit class of 50, indicating a medium-fit tolerance appropriate for general industrial fastening. Licensed trades including HVAC technicians, plumbers, and electricians use this type of hardware when assembling equipment frames, mounting components, or securing panels where a continuous threaded connector is required.

This stud is appropriate for use in both light commercial and residential trade applications wherever a 1/4-20 threaded fastener with equal engagement on both ends is specified. Typical installation scenarios include equipment mounting, bracket assemblies, and panel attachment in HVAC, plumbing, and electrical enclosure work. The black oxide finish provides mild corrosion resistance in dry or lightly humid indoor environments. No flat is included on this stud, so standard hex nuts or coupling nuts are used for installation and removal.

Key Features

• Equal double threaded design provides consistent thread engagement on both ends
• 1/4-20 thread size is a widely standardized fastener dimension across trade applications
• Alloy steel construction with grade 5 material rating for reliable tensile strength
• Black oxide finish offers mild corrosion resistance and reduces surface glare
• Thread fit class 50 ensures medium-tolerance fit with standard 1/4-20 nuts and couplers
• No flat design — compatible with standard hex nuts and coupling nuts

Compatibility

Designed as a standard 1/4-20 equal double threaded stud for use with any application specifying that thread size and a 4.5-inch overall length in alloy steel construction.

Installation Notes

Installation of double threaded studs should be performed with the appropriate fastener drive tools and mating nuts rated for the thread fit class. Power down or de-energize any equipment before installing or removing fasteners in electrical or mechanical enclosures. Do not overtighten mating nuts on alloy steel studs without a torque specification from the equipment manufacturer. Follow applicable mechanical codes and equipment service documentation for proper fastener selection and installation procedure.
