Gibraltar ST2-70-G Equal Double Threaded Stud 1/2-13 7 in

Product Description

The GIBRALTAR ST2-70-G is an equal double threaded stud designed for secure, two-directional fastening in mechanical assemblies, structural connections, and industrial applications. Machined from grade 1117 carbon steel with a black oxide finish, this stud resists corrosion and surface wear under typical shop and field conditions. At 7 inches overall length with 1/2-13 threads on both ends in left and right thread directions, it provides a stable, load-bearing connection point where a bolt or nut engages on each side. Plumbers, pipefitters, HVAC technicians, and general mechanical tradespeople use this type of hardware when installing equipment flanges, pipe supports, and structural mounting brackets.

This stud suits residential and light commercial applications requiring a reliable threaded anchor or through-connection point. Common installations include equipment mounting pads, valve flanges, pipe hangers, and structural support frames where both ends must accept threaded fasteners simultaneously. The equal thread configuration ensures consistent engagement depth on each side of the joint, supporting balanced load distribution across the connection.

Key Features

• Equal double-end thread configuration with left and right thread direction for two-sided engagement
• 1/2-13 thread size on both ends for standard nut and coupling compatibility
• 7 inches overall length for medium-depth through-bolting and standoff applications
• Grade 1117 carbon steel construction for strength and machinability in fastener applications
• Black oxide finish reduces surface corrosion and provides a uniform appearance
• Lightweight at 0.3 pounds, reducing added load in overhead or suspended assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fastener for mechanical and structural assemblies requiring a 1/2-13 equal double threaded stud at 7 inches overall length.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, HVAC mechanics, or general mechanical contractors. De-energize and de-pressurize any system before fastener removal or replacement. Use appropriate wrenches or stud drivers to avoid damaging thread form, and verify that mating threads are clean and free of debris before assembly. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the surrounding assembly.
