Gibraltar 40574G Double Threaded Stud 3/8-16 3in Stainless

Product Description

The GIBRALTAR 40574G is an equal double threaded stud designed for secure fastening in applications where both ends require threaded engagement. This stud features a 3/8-16 unified coarse thread on both ends with an overall length of 3 inches. Manufactured from 303 stainless steel with a black oxide finish, it provides solid corrosion resistance and a Class 50 thread fit for reliable clamping force. No flat is machined onto the body, keeping the shank profile clean. Trade professionals in HVAC, plumbing, and light structural assembly commonly specify this type of fastener where a bolt head would be inaccessible or unwanted.

This double threaded stud is suited for residential and commercial mechanical installations where two components must be clamped together from a single threaded anchor point. Typical applications include equipment mounting, vibration-isolated assemblies, and bracket-to-panel connections. The equal thread configuration means both ends share the same 3/8-16 thread size and engagement depth, simplifying nut and coupling selection on both sides of the joint.

Key Features

• Equal double threaded configuration with identical 3/8-16 thread on both ends
• 3 inches overall length for standard-depth fastening applications
• 303 stainless steel construction for corrosion resistance
• Black oxide finish reduces surface reflectivity and adds mild additional protection
• Class 50 thread fit ensures consistent engagement and holding force
• No flat on the shank for a clean, unobstructed profile

Compatibility

Designed as a standard-style equal double threaded stud for use wherever a 3/8-16 threaded fastener with 3 inches overall length is required in mechanical and trade installations.

Installation Notes

Installation is typically performed by licensed mechanical or HVAC technicians using two nuts run to a jam-nut configuration or by threading into a tapped hole on one end. De-energize and isolate equipment before fastener work near electrical or pressurized systems. Use the appropriate torque wrench for the joint material to avoid galling on stainless steel threads; applying anti-seize compound to stainless fasteners is standard practice to prevent thread seizure.
