Gibraltar ST2-22-G Double Threaded Stud 1/2-13 2-1/4in

Product Description

The GIBRALTAR ST2-22-G is an equal double threaded stud with a 1/2-13 thread size and an overall length of 2-1/4 inches. It is manufactured from grade 1117 carbon steel and carries a black oxide finish that provides a base level of corrosion resistance in typical indoor and light-duty applications. The stud features left and right thread directions on each end, making it a true equal double-end configuration. This type of fastener is used by mechanical contractors, pipefitters, HVAC technicians, and maintenance professionals wherever a threaded connection point is needed on both ends of a single fastener.

Equal double threaded studs like the ST2-22-G are commonly used in equipment mounting, flanged connections, and mechanical assembly applications found in commercial and light industrial settings. The 1/2-13 unified coarse thread is a widely used standard thread pitch, suited for use with standard hex nuts and flanged hardware in HVAC equipment, plumbing fixtures, and general mechanical systems. The compact 2-1/4 inch overall length makes it well-suited for assemblies with limited bolt-length clearance.

Key Features

• Equal double threaded design with left and right threaded ends for two-point fastening
• 1/2-13 unified coarse thread — compatible with standard 1/2-inch hardware
• Grade 1117 carbon steel construction for reliable tensile strength in mechanical assemblies
• Black oxide finish for a uniform appearance and mild corrosion resistance
• 2-1/4 inch overall length suits tight-clearance mounting applications

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1/2-13 equal double threaded stud with a 2-1/4 inch overall length.

Installation Notes

Installation is typically performed by mechanical contractors, HVAC technicians, or maintenance personnel using standard hand tools. Ensure mating threads and receiving hardware are free of debris and damage before assembly. Apply appropriate thread lubricant or thread-locking compound as required by the application. Do not overtighten, as carbon steel studs can be susceptible to thread damage if torqued beyond the rated capacity of the joint.
