Gibraltar 40474G Double Threaded Stud 5/16-18 3 Inch

Product Description

The GIBRALTAR 40474G is an equal double threaded stud with a 5/16-18 thread size and a 3-inch overall length. Made from Grade 303 stainless steel with a black oxide finish, this stud provides corrosion resistance and consistent clamping performance in demanding trade applications. The Class 50 thread fit ensures reliable engagement across both ends of the stud. It is a standard fully threaded fastener used by HVAC technicians, plumbers, electricians, and mechanical contractors wherever a double-end stud connection is required in metal assembly or equipment mounting.

This double threaded stud is suited for use in residential and commercial mechanical systems where secure, vibration-resistant fastening is needed. The equal thread configuration means both ends share the same 5/16-18 thread specification, making it straightforward to use in symmetrical mounting and bracketing applications. The black oxide finish reduces surface reflectivity and provides mild corrosion protection in dry or lightly humid environments. Typical install scenarios include equipment brackets, panel mounts, and component assemblies in HVAC, plumbing, and electrical enclosure work.

Installation Notes

Installation of threaded studs is performed by mechanical contractors, HVAC technicians, plumbers, and electricians depending on the application. De-energize or shut off the relevant system before fastener work on live equipment. Use the appropriate driver or stud installation tool to avoid thread damage. Follow applicable mechanical and structural codes for fastener torque and assembly requirements.
