Gibraltar ST0-40-G Double Threaded Stud 1/4-20 4 Inch

Product Description

The GIBRALTAR ST0-40-G is an equal double threaded stud with a 1/4-20 thread size and a 4-inch overall length. This fastener features threading on both ends in left and right directions, allowing it to mate with two separate threaded components simultaneously. Manufactured from 1117 grade carbon steel with a black oxide finish, it provides moderate corrosion resistance and a clean, low-reflectance appearance. Weighing 0.04 pounds, this compact stud is suited for light-duty mechanical assemblies, HVAC equipment mounting, electrical enclosures, and plumbing fixture connections where a stud-style fastener is required instead of a conventional bolt.

This stud is commonly used in residential and light commercial applications where two components need to be fastened to a central threaded point. Typical install scenarios include equipment brackets, panel supports, and mechanical assemblies that require removable, threaded connections. It is sold individually and is appropriate for contractors, maintenance technicians, and tradespeople who need a standard inch-thread double stud in a commonly stocked size.

Key Features

• Equal double threaded design with left and right thread direction for dual-end fastening
• 1/4-20 UNC thread size — a widely used standard inch thread
• 4-inch overall length for versatile fitment in bracket and panel applications
• 1117 grade carbon steel construction for reliable mechanical strength
• Black oxide finish reduces surface reflectance and provides light corrosion protection

Compatibility

Designed as a standard 1/4-20 equal double threaded stud for use in mechanical assemblies, equipment mounting brackets, and structural connections requiring an inch-thread stud fastener.

Installation Notes

Installation is performed by threading one end of the stud into the primary component before attaching the mating part to the exposed end. Use an appropriately sized stud driver or locking nut method to install without damaging the threads. Ensure the receiving threads are clean and free of debris before installation. Follow applicable mechanical codes and equipment manufacturer guidelines for torque and fastener specifications.
