Gibraltar ST2-20-G Double Threaded Stud 1/2-13 2 in

Product Description

The GIBRALTAR ST2-20-G is an equal double threaded stud with a 1/2-13 thread size and a 2-inch overall length. This stud features left and right-hand threads on both ends, allowing it to be threaded into a tapped hole on one end while accepting a nut or mating component on the other. Manufactured from 1117 carbon steel with a black oxide finish, it provides moderate corrosion resistance suitable for indoor mechanical and structural fastening applications. Electricians, plumbers, HVAC technicians, and general contractors use this type of fastener when a fixed stud anchor point is required in metal or threaded assemblies.

This equal double threaded stud is appropriate for light industrial, commercial, and residential mechanical applications where a permanent or semi-permanent threaded connection point is needed. It is commonly used in equipment mounting, pipe support hangers, HVAC equipment frames, and general fabrication work. The 1/2-13 UNC thread is one of the most common coarse-thread sizes in North American trade applications, making mating hardware widely available.

Key Features

• Equal thread configuration with left and right-hand threads on both ends for versatile installation
• 1/2-13 UNC thread size — standard coarse-thread pitch widely used in mechanical and structural fastening
• 2-inch overall length suits shallow mounting depth applications
• 1117 carbon steel construction provides good machinability and tensile strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection in service environments

Compatibility

Designed as a standard 1/2-13 UNC equal double threaded stud for use with any mating hardware or tapped hole conforming to the 1/2-13 unified coarse thread standard.

Installation Notes

Installation typically requires a stud driver, two jam nuts, or locking pliers to drive the stud into the receiving tapped hole. Power down or de-energize any equipment before installing studs in electrical enclosures or live panels. Follow applicable mechanical codes and torque practices for the assembly type. Avoid cross-threading by starting the stud by hand before applying tool torque.
