Gibraltar 40809G Equal Double Threaded Stud 5/8-11 5.5 in

Product Description

The GIBRALTAR 40809G is an equal double threaded stud designed for fastening applications where a fixed, threaded anchor point is required on both ends. Manufactured from alloy steel with a black oxide finish, this stud measures 5.5 inches overall length and carries a 5/8-11 thread size with a Grade 5 material rating and Thread Fit Class 50. The flat feature ensures consistent seating and alignment during assembly. At 0.5 pounds, it is well-suited for structural and mechanical fastening tasks performed by millwrights, pipefitters, and general trade mechanics in both industrial and commercial settings.

This double threaded stud is appropriate for use in equipment mounting, flange connections, and structural assemblies where a stud must engage two separate threaded components simultaneously. The 5/8-11 coarse thread pattern is a standard size common in heavy mechanical and industrial applications. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. It is typically installed in shop or field conditions where Grade 5 alloy fasteners are specified by engineering or maintenance standards.

Key Features

• Equal double threaded design — identical 5/8-11 thread on both ends for symmetrical engagement
• Alloy steel construction with Grade 5 material rating for reliable tensile strength
• Black oxide finish for mild corrosion resistance and clean appearance
• Thread Fit Class 50 for controlled thread tolerance and consistent fit
• Flat feature included for proper seating and torque reference
• 5.5 inch overall length suits a range of standard mounting depths

Compatibility

Designed as a standard-pattern replacement or new-installation fastener for mechanical and structural assemblies requiring a 5/8-11 coarse thread equal double threaded stud in Grade 5 alloy steel.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or pipefitters using standard hand tools and torque wrenches rated for Grade 5 fastener specifications. Always de-energize and lock out equipment before installing or removing threaded studs in powered assemblies. Thread engagement depth on both ends should meet the minimum specified by the joint design or applicable engineering standard. Do not exceed the torque specification called out in the equipment service documentation.
