Gibraltar 40703G Equal Double Threaded Stud 1/2-13 2-1/2 in

Product Description

The GIBRALTAR 40703G is an equal double threaded stud with a 1/2-13 thread size and an overall length of 2-1/2 inches. This fastener features identical threads on both ends, allowing it to be threaded into a fixed 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 rated at material grade 5, it delivers solid tensile strength and moderate corrosion resistance in mechanical and structural assembly applications. Electricians, plumbers, HVAC technicians, and general maintenance trades use double threaded studs where a bolt head would be impractical or where two components must be joined through a threaded interface.

This stud is suited for use in residential and light commercial mechanical installations, equipment mounting, pipe flange assemblies, and structural hardware connections. The 1/2-13 UNC thread form is one of the most common coarse-thread standards in North American trade work, making this stud compatible with widely available nuts, couplers, and tapped fittings of the same thread specification. It is a single-piece fastener sold individually and appropriate for applications where a removable, double-ended threaded connection is required.

Key Features

• Equal thread configuration on both ends for symmetric installation and load distribution
• 1/2-13 UNC coarse thread for broad compatibility with standard North American hardware
• Alloy steel construction at material grade 5 for reliable tensile and shear strength
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Thread fit class 50 for consistent engagement tolerances
• No flat, allowing full engagement in tapped holes without wrench flats interfering

Compatibility

Designed as a standard 1/2-13 UNC equal double threaded stud for use in mechanical assemblies, equipment mounting, and structural fastening applications where this thread size and overall length are specified.

Installation Notes

Installation is typically performed by a mechanic, pipefitter, or maintenance technician using standard hand tools rated for 1/2-13 hardware. Always de-energize, depressurize, or shut down the system being serviced before installing or removing threaded fasteners in load-bearing or pressurized assemblies. Use a thread-engagement depth appropriate to the base material to ensure pull-out strength. Do not overtighten; apply torque per the equipment manufacturer's specification for the mating assembly.
