Gibraltar 40313G Double Threaded Stud 1/4-20 7.5 in Alloy Steel

Product Description

The GIBRALTAR 40313G is an equal double threaded stud with a 1/4-20 thread size and an overall length of 7.5 inches. It is machined from alloy steel with a black oxide finish and carries a Grade 5 material rating and Thread Fit Class 50. Double threaded studs are externally threaded on both ends with equal thread lengths, making them a standard fastener for through-bolting, assembly work, and securing components where a bolt head is not practical. This part is installed by electricians, HVAC technicians, plumbers, and general trade professionals in mechanical and structural assembly applications.

This stud is suited for light industrial, commercial, and residential trade applications where a reliable threaded connection is needed on both ends of the fastener. The black oxide finish provides a degree of corrosion resistance in dry or mildly humid environments. Equal thread configuration means both ends have the same thread engagement length, making it interchangeable end-to-end during installation. Typical applications include equipment mounting, panel assembly, and mechanical fixture work.

Key Features

• Equal double threaded on both ends with 1/4-20 thread size
• 7.5 inch overall length suits through-bolt and standoff applications
• Alloy steel construction with Grade 5 material rating
• Black oxide finish for mild corrosion resistance
• Thread Fit Class 50 for consistent thread engagement
• No flat — fully threaded along both working ends

Compatibility

Designed as a standard 1/4-20 equal double threaded stud for use in mechanical assemblies, equipment mounting, and trade installation applications requiring dual external thread engagement.

Installation Notes

Installation is performed by hand-threading one end into a tapped hole or coupling nut before securing the mating component on the opposite end. Use appropriate thread-locking compound or hardware per the assembly specification. Always verify thread engagement depth meets the fastener manufacturer and applicable code requirements before applying load. Wear appropriate PPE when working with fasteners in overhead or high-torque applications.
