Gibraltar 40306G Equal Double Threaded Stud 1/4-20 4 in

Product Description

The GIBRALTAR 40306G is an equal double threaded stud with a 1/4-20 thread size and an overall length of 4 inches. This stud features threads of equal length on both ends, allowing it to be threaded into a tapped hole on one end while accepting a nut or mating component on the other. Constructed from alloy steel with a black oxide finish and a material grade of 5, it delivers solid mechanical strength and basic corrosion resistance in a compact fastener form. Licensed trades and maintenance technicians use double threaded studs in mechanical assemblies, equipment mounting, and structural fastening applications across HVAC, electrical, and general industrial work.

This stud is suited for light to medium-duty mechanical fastening in both residential and commercial trade settings. The 1/4-20 thread is one of the most common unified coarse thread sizes in North American trade applications, making this stud compatible with a wide range of standard nuts, couplers, and tapped components. It is a single-piece sold individually and is appropriate wherever a permanent or semi-permanent threaded connection point is required in metal assemblies or equipment enclosures.

Key Features

• Equal double threaded design with 1/4-20 thread on both ends for bidirectional engagement
• 4-inch overall length provides extended reach in deep assemblies or standoff applications
• Alloy steel construction with material grade 5 for reliable mechanical strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread fit class 50 ensures consistent tolerance and proper mating with standard hardware
• No flat ground into the shank, maintaining full thread engagement along the stud body

Compatibility

Designed as a standard replacement or new-installation fastener for applications requiring a 1/4-20 unified coarse thread double-ended stud in alloy steel construction.

Installation Notes

Installation is typically performed by licensed technicians or maintenance trades using standard hand tools such as a stud driver, locking pliers, or double-nut method. Ensure the receiving tapped hole meets 1/4-20 thread specifications before installation. Power down and de-energize any equipment before fastening components to live electrical or mechanical assemblies. Verify thread engagement depth meets applicable mechanical code requirements for the load rating of the assembly.
