Gibraltar 74363870 Equal Double Threaded Stud 1-8 Thread 4 in

Product Description

The GIBRALTAR 74363870 is an equal double threaded stud with a 1-8 UNC thread size and a 4-inch overall length. It is manufactured from alloy steel with a black oxide finish, providing corrosion resistance and a uniform appearance. The Thread Fit Class 2A designation indicates a standard external thread tolerance suitable for general-purpose mechanical and structural fastening applications. This stud is typically installed by millwrights, maintenance technicians, pipefitters, or mechanical contractors working with heavy equipment, flanged connections, or structural assemblies requiring a fully threaded double-end fastener.

Equal double threaded studs of this size are used in industrial and commercial settings where a bolt cannot be passed through from one side, or where a removable connection is needed on both ends. Common applications include machinery mounting, equipment flanges, pump housings, and heavy-duty fastening where the stud remains in place and nuts are threaded onto both exposed ends. The 1-8 thread size is suited for high-load connections in steel fabrication and mechanical assembly work.

Key Features

• Equal thread length on both ends allows nuts or couplings to engage fully from either side
• 1-8 UNC thread size provides coarse pitch for high-load fastening in structural and mechanical applications
• Alloy steel construction offers higher tensile strength compared to standard carbon steel fasteners
• Black oxide finish reduces surface corrosion and light oxidation in dry or mildly humid environments
• Thread Fit Class 2A ensures compatibility with standard Class 2B tapped holes and nuts
• 4-inch overall length suits medium-depth through-connections and flange assemblies

Compatibility

Designed as an OEM-style replacement or standard replacement fastener for industrial and mechanical assemblies requiring a 1-8 UNC equal double threaded stud with a 4-inch overall length in alloy steel.

Installation Notes

Installation is typically performed by a licensed millwright or mechanical technician. De-energize and lock out all equipment before installing or removing studs in powered assemblies. Use an appropriate stud driver or double-nut method to install without damaging threads. Verify tapped hole thread class compatibility before installation to ensure proper fit and load rating.
