Gibraltar 40507G Double Threaded Stud 3/8-16 4.5 in

Product Description

The GIBRALTAR 40507G is an equal double threaded stud with a 3/8-16 thread size and an overall length of 4.5 inches. It is constructed from alloy steel with a black oxide finish, providing corrosion resistance and a consistent surface for secure fastening. This stud features a flat and meets Thread Fit Class 50 standards, making it suitable for demanding mechanical and structural fastening applications. Plumbers, HVAC technicians, electricians, and general mechanical contractors use double threaded studs to create fixed threaded anchor points in assemblies where both ends require nut engagement.

This stud is appropriate for residential and light commercial mechanical applications where a reliable, equal-length double-end threaded fastener is required. Typical installations include equipment mounting, pipe support brackets, panel assemblies, and structural connections where through-bolting is not an option and both ends of the fastener must accept a nut. The black oxide finish suits indoor and sheltered installations across HVAC, plumbing, and electrical panel work.

Key Features

• Equal double threaded design with matching thread engagement on both ends
• 3/8-16 UNC thread size for broad fastener compatibility
• 4.5-inch overall length suits medium-depth mounting applications
• Alloy steel construction with Material Grade 5 for high tensile strength
• Black oxide finish for corrosion resistance in sheltered environments
• Flat included for controlled positioning during installation

Compatibility

Designed as a standard 3/8-16 UNC equal double threaded stud for use in mechanical, HVAC, plumbing, and electrical fastening assemblies requiring a Grade 5 alloy steel stud with Thread Fit Class 50.

Installation Notes

Installation of double threaded studs is typically performed by licensed mechanical, HVAC, or plumbing technicians using standard hand tools and a stud driver or locking nut method. De-energize and de-pressurize any system before fastening or replacing studs in live assemblies. Verify thread engagement depth and nut torque requirements per the equipment manufacturer specifications. Follow applicable mechanical codes for the jurisdiction when used in structural or pressure-boundary connections.
