Gibraltar ST2-30-G Double Threaded Stud 1/2-13 3 Inch

Product Description

The GIBRALTAR ST2-30-G is an equal double threaded stud with a 1/2-13 thread size and an overall length of 3 inches. This stud features left and right thread directions — meaning both ends carry the same 1/2-13 thread — making it suitable for applications that require a fixed connection point on both sides of an assembly. Constructed from 1117 grade carbon steel with a black oxide finish, it offers reliable mechanical strength with moderate corrosion resistance in controlled environments. Electricians, plumbers, HVAC technicians, and general tradespeople commonly use double threaded studs as fasteners in equipment mounting, pipe hangers, and mechanical assemblies.

This stud is appropriate for use in residential and light commercial mechanical applications where a 1/2-13 UNC fastener is specified. The equal-thread configuration allows nuts to be threaded onto either end without requiring a dissimilar thread match, simplifying assembly in tight or repetitive fastening scenarios. The black oxide finish is suited for dry or lightly oiled indoor environments. Typical applications include equipment mounting brackets, threaded rod assemblies, and general fabrication work encountered in HVAC, plumbing, and electrical service.

Key Features

• 1/2-13 UNC thread on both ends — equal double threaded configuration
• 3 inch overall length for standard mid-range fastening applications
• 1117 grade carbon steel for consistent machinability and tensile strength
• Black oxide finish provides mild corrosion resistance in indoor environments
• Left and right thread direction on a single stud body
• Weighs 0.13 pounds — lightweight for easy handling and inventory

Compatibility

Designed as a standard 1/2-13 UNC double threaded stud for use in general mechanical, HVAC, plumbing, and electrical fastening assemblies where this thread size and 3 inch overall length are specified.

Installation Notes

Install using appropriately sized wrenches or a stud driver rated for 1/2-13 fasteners. De-energize and depressurize any system before replacing or installing fasteners in live assemblies. Verify thread engagement depth meets the requirements of the host material before applying load. Black oxide finishes are not a substitute for plated or stainless hardware in wet or corrosive environments.
