Gibraltar ST1-45-G Double Threaded Stud 3/8-16 4.5 in

Product Description

The GIBRALTAR ST1-45-G is an equal double threaded stud with a 3/8-16 thread size and a 4.5-inch overall length. Machined from grade 1117 carbon steel with a black oxide finish, this stud provides corrosion resistance and consistent thread engagement on both ends. The equal-length thread configuration means both threaded sections are the same length, making it straightforward to use in symmetric fastening applications. Left and right thread direction is supported, meaning both ends accept standard right-hand threaded fasteners. Installers across HVAC, plumbing, and mechanical trades rely on double threaded studs for panel mounting, bracket attachment, and equipment anchoring tasks where a bolt cannot pass fully through an assembly.

This stud is suited for residential and light commercial mechanical installations where a reliable two-sided threaded fastener is required. Typical applications include mounting brackets, securing equipment flanges, and assembling structural mechanical components. The black oxide finish reduces surface corrosion in indoor and sheltered environments. The 3/8-16 thread size is one of the most common coarse-thread fastener sizes used in trade work, making this stud compatible with widely available hex nuts, locknuts, and coupling hardware.

Key Features

• Equal double threaded configuration with left and right thread direction on both ends
• 3/8-16 coarse thread size for broad compatibility with standard trade hardware
• 4.5-inch overall length suits medium-depth mounting and fastening applications
• Grade 1117 carbon steel construction for reliable mechanical strength
• Black oxide finish provides surface protection in dry and sheltered environments

Compatibility

Designed as a general-purpose equal double threaded stud for use with standard 3/8-16 threaded nuts, coupling hardware, and mechanical assemblies in HVAC, plumbing, and light structural applications.

Installation Notes

Installation is performed with standard hex wrenches or a stud driver sized for 3/8-16 fasteners. Ensure mating surfaces are clean and free of burrs before threading to avoid galling the carbon steel. Torque to the value specified by the equipment manufacturer or applicable mechanical assembly standard. Apply thread-locking compound or jam nuts as required by the assembly to prevent loosening under vibration.
