Gibraltar 40807G Double Threaded Stud 5/8-11 4.5 in Oal

Product Description

The GIBRALTAR 40807G is an equal double threaded stud with a 5/8-11 thread size and an overall length of 4.5 inches. Manufactured from alloy steel with a black oxide finish, this stud is rated to Thread Fit Class 50 and carries a Material Grade 5 designation, making it suitable for structural and mechanical fastening applications where consistent clamping force and thread engagement are required. The black oxide finish provides moderate corrosion resistance in dry or lightly oiled environments. A flat is included on the shank for secure engagement during installation. This fastener is installed by millwrights, pipefitters, electricians, and general mechanical trades across industrial and commercial settings.

This double threaded stud is used in applications where a bolt cannot be passed through both mating components, such as mounting brackets, equipment bases, flanged assemblies, and machine frames. The equal thread configuration means both ends carry the same 5/8-11 thread, allowing nuts or threaded components to be engaged from either side. It is appropriate for residential, commercial, and light industrial mechanical assemblies requiring a Grade 5 alloy steel fastener at this thread size.

Key Features

• Equal double threaded design with matching 5/8-11 threads on both ends
• Alloy steel construction with Material Grade 5 rating for reliable mechanical strength
• Black oxide finish for moderate corrosion resistance in dry or lightly lubricated environments
• Thread Fit Class 50 for consistent fit and engagement in standard threaded assemblies
• Flat on shank for controlled installation with standard hand tools
• 4.5 inch overall length suits a range of bracket and flange mounting depths

Compatibility

Designed as a standard-fit replacement or new-installation fastener for mechanical assemblies requiring a 5/8-11 equal double threaded stud at 4.5 inches overall length in alloy steel.

Installation Notes

Installation is performed by qualified mechanical trades using a double-nut or stud-driver method to engage the stud into the threaded base component without damaging the exposed thread. Ensure all mating threads are clean and free of debris before installation. De-energize or lock out any equipment before servicing fasteners on live mechanical assemblies per applicable OSHA lockout/tagout procedures. Apply thread lubricant or anti-seize compound as required by the assembly specification to achieve accurate torque on the mating nut.
