Gibraltar ST1-35-G Double Threaded Stud 3/8-16 3.5 Inch

Product Description

The GIBRALTAR ST1-35-G is an equal double threaded stud with a 3/8-16 thread size and an overall length of 3.5 inches. Manufactured from 1117-grade carbon steel with a black oxide finish, this stud provides corrosion resistance and a consistent thread engagement on both ends. The equal configuration means both threaded sections are identical in length and thread specification, making it suitable for fastening applications where a continuous connection between two components is required. It is used by maintenance technicians, millwrights, and tradespeople in mechanical assembly and repair work across HVAC, plumbing, and general industrial environments.

This stud is appropriate for residential and commercial mechanical installations where a reliable, double-ended fastener is needed. The 3/8-16 unified coarse thread pattern is a common standard size found in structural brackets, equipment mounting, and pipe support assemblies. The left and right thread direction noted in the specifications confirms standard right-hand threading on both ends. The black oxide finish provides mild surface protection suited for indoor and protected-environment installations.

Key Features

• Equal double threaded design with identical thread engagement on both ends
• 3/8-16 unified coarse thread for broad fastener compatibility
• 1117-grade carbon steel construction for reliable tensile strength
• Black oxide finish for mild corrosion resistance in protected environments
• Compact 3.5-inch overall length suits tight clearance installations

Compatibility

Designed as a standard 3/8-16 double threaded stud for use in general mechanical, HVAC, plumbing, and structural fastening applications requiring an equal stud configuration.

Installation Notes

Installation is performed with standard hex nuts, stud drivers, or locking pliers appropriate for 3/8-16 fasteners. Ensure both mating threaded components are clean and free of debris before threading the stud into place. Apply thread-locking compound or anti-seize as required by the application and applicable codes. Do not overtighten, as carbon steel studs are subject to shear failure if torque limits are exceeded without proper fastener engineering data.
