Gibraltar ST1-20-G Double Threaded Stud 3/8-16 2 in

Product Description

The GIBRALTAR ST1-20-G is an equal double threaded stud with a 3/8-16 thread size and a 2-inch overall length. Machined from 1117 grade carbon steel and finished in black oxide, this stud provides corrosion resistance and consistent thread engagement on both ends. The left and right thread direction on each end allows the stud to be threaded into a tapped hole on one side and accept a nut or coupling on the other. It is commonly installed by millwrights, pipefitters, HVAC technicians, and general mechanical tradespeople wherever a fixed threaded anchor point is required in an assembly or equipment housing.

This double threaded stud is suited for use in light to medium-duty mechanical assemblies, HVAC equipment panels, plumbing fixture mounting, and electrical enclosure hardware. Its equal-length thread configuration on both ends makes it appropriate for applications requiring balanced thread engagement depth from each face. The black oxide finish is compatible with both indoor and sheltered outdoor installations where minimal surface protection is acceptable.

Key Features

• Equal double threaded design with left and right thread direction for dual-end engagement
• 3/8-16 UNC thread size for broad compatibility with standard fastener hardware
• 2-inch overall length suits compact mounting and panel applications
• 1117 grade carbon steel construction for reliable strength in mechanical assemblies
• Black oxide finish reduces surface corrosion in dry and sheltered environments

Compatibility

Designed as a standard 3/8-16 equal double threaded stud for use in mechanical, HVAC, plumbing, and electrical assemblies requiring a fixed threaded anchor point with dual-end thread engagement.

Installation Notes

Installation is typically performed by a qualified mechanic, millwright, or trade technician using standard thread-engagement practices. De-energize and isolate any equipment before installing or removing threaded studs in live assemblies. Use appropriate thread-locking compound or torque specifications as defined by the equipment manufacturer. Inspect mating tapped holes for thread condition before installation to avoid cross-threading or stud failure.
