Gibraltar 74363391 Double Threaded Stud 3/8-16 6in

Product Description

The GIBRALTAR 74363391 is an equal double threaded stud with a 3/8-16 thread size and a 6-inch overall length. This stud is machined from alloy steel and finished in black oxide for corrosion resistance and a uniform appearance. The 3/8-16 thread runs on both ends in equal lengths, allowing the stud to be threaded into a fixed base while accepting a nut or fitting on the opposing end. Thread fit is Class 2A, which designates an external thread tolerance standard suitable for general-purpose mechanical and structural fastening applications. Plumbers, pipefitters, HVAC technicians, and maintenance trades use studs of this type for mounting equipment, securing flanges, and anchoring mechanical assemblies.

This double threaded stud is suited for residential and commercial mechanical installations where a permanent or semi-permanent threaded anchor point is required. Typical applications include equipment mounting brackets, flanged connections, and structural fastening in HVAC, plumbing, and general industrial settings. The alloy steel construction supports use in moderate-load applications where carbon steel fasteners may be insufficient. The black oxide finish provides mild corrosion resistance appropriate for interior and sheltered exterior environments.

Key Features

• Equal thread length on both ends for symmetrical engagement
• 3/8-16 UNC thread size, Class 2A fit for general mechanical use
• 6-inch overall length suits medium-depth mounting and flange applications
• Alloy steel construction offers higher tensile strength than standard carbon steel
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard 3/8-16 equal double threaded stud for general mechanical fastening applications requiring a 6-inch overall length alloy steel stud with Class 2A thread fit.

Installation Notes

Installation is typically performed by a qualified mechanical, HVAC, or plumbing technician. De-energize all electrical circuits and shut off relevant fluid or gas supply lines before installing fasteners in active mechanical systems. Use appropriate thread-locking compound or anti-seize as required by the application and applicable codes. Do not exceed the rated load for the fastener diameter and material grade.
