Gibraltar ST2-80-G Equal Double Threaded Stud 1/2-13 8 in

Product Description

The GIBRALTAR ST2-80-G is an equal double threaded stud with a 1/2-13 thread size and an overall length of 8 inches. It is machined from 1117 carbon steel and finished in black oxide for mild corrosion resistance and a clean appearance. The equal double threaded design means both ends carry the same thread specification, making it a straightforward choice for through-bolting, tensioning, and fastening applications in mechanical and industrial assemblies. Licensed tradespeople and maintenance technicians install this type of stud wherever a fully threaded, double-end fastener is required in place of a standard bolt or cap screw.

This stud is suited for use in HVAC equipment frames, plumbing fixture mounting, electrical enclosure assemblies, and general mechanical fabrication where 1/2-13 UNC thread engagement is needed on both ends. The black oxide finish is compatible with standard installation environments found in residential and light commercial mechanical rooms. The 8-inch overall length accommodates thicker assemblies or applications requiring significant thread engagement depth on one or both ends.

Key Features

• Equal double threaded ends — both ends are 1/2-13 UNC for interchangeable engagement
• 8-inch overall length provides flexibility for deep or stacked assemblies
• 1117 carbon steel construction for reliable tensile strength in mechanical fastening
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Left and right thread direction on respective ends for standard installation practice

Compatibility

Designed as a standard equal double threaded stud for use in any mechanical, HVAC, plumbing, or electrical assembly requiring a 1/2-13 UNC thread pattern with an 8-inch overall length.

Installation Notes

Installation of double threaded studs is typically performed by licensed mechanics, HVAC technicians, or plumbers using standard hand tools and a stud driver or two-nut method. Always de-energize equipment and relieve any system pressure before removing or replacing fasteners in an active assembly. Apply thread lubricant or anti-seize compound as required by the equipment manufacturer to prevent galling on carbon steel threads. Follow applicable torque specifications provided by the equipment OEM for the fastened assembly.
