Gibraltar 40304G Equal Double Threaded Stud 1/4-20 3 in

Product Description

The GIBRALTAR 40304G is an equal double threaded stud designed for secure fastening in mechanical, electrical, and light structural assemblies. Manufactured from alloy steel with a black oxide finish, this stud measures 3 inches overall length and is threaded 1/4-20 on both ends with equal thread engagement. The black oxide finish provides mild corrosion resistance and reduces light reflection. Grade 5 material and Thread Fit Class 50 construction make this stud suitable for general-purpose fastening applications where consistent clamping force is required. Installers in HVAC, plumbing, and electrical trades use double threaded studs for mounting brackets, standoffs, and component assemblies.

This stud is appropriate for residential and light commercial applications where a 1/4-20 threaded connection is specified. It fits standard 1/4-20 nuts and threaded inserts, making it compatible with a wide range of mounting scenarios including panel mounting, bracket fabrication, and equipment standoff assemblies. The equal-thread configuration means both ends engage the same thread pitch and depth, eliminating the need to track a drive end versus a stud end during installation.

Key Features

• Equal double threaded design — both ends are 1/4-20 for symmetric engagement
• Alloy steel construction with Grade 5 material rating for reliable tensile strength
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Thread Fit Class 50 for consistent fit with standard 1/4-20 hardware
• 3 inches overall length suitable for moderate standoff and through-mount applications
• Sold individually — Pkg Qty 1

Compatibility

Designed as a general-purpose replacement or new-installation fastener for any application specifying a 1/4-20 equal double threaded stud with a 3-inch overall length.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or plumbers during equipment assembly or bracket mounting. Power down or de-energize any equipment before installing or removing studs near live electrical components. Use appropriately sized wrenches or drivers — avoid over-torquing alloy steel studs into softer base materials such as aluminum or sheet metal. Verify thread engagement depth on both ends before applying final load.
