Gibraltar 41004G Equal Double Threaded Stud 7/8-9 4.5 in

Product Description

The GIBRALTAR 41004G is an equal double threaded stud designed for secure fastening applications where both ends require identical thread engagement. Manufactured from alloy steel with a black oxide finish, this stud measures 4.5 inches overall length with a 7/8-9 thread size on both ends. The flat feature allows for controlled installation and removal with standard tooling. A Thread Fit Class of 50 and Material Grade 5 designation confirm this stud meets recognized mechanical strength standards for demanding industrial and structural fastening jobs. Maintenance technicians, millwrights, and trade professionals working with heavy equipment or structural assemblies are the primary installers.

Equal double threaded studs like the 41004G are used in mechanical assemblies where a bolt cannot pass fully through a joint, or where a fixed stud is needed on both faces of a component. Typical applications include equipment mounting, flange connections, structural bracing, and machinery repair in industrial, commercial, and heavy trade settings. The black oxide finish provides moderate corrosion resistance and reduces light reflection, making it suitable for both indoor and outdoor environments where exposure is limited.

Key Features

• Equal thread engagement on both ends — 7/8-9 UNC thread size throughout
• Alloy steel construction with Material Grade 5 for high tensile strength
• Black oxide finish provides corrosion resistance and a low-glare surface
• Thread Fit Class 50 ensures consistent thread tolerance and reliable fitment
• Flat feature allows wrench engagement for controlled installation and extraction
• 4.5-inch overall length suits deep or multi-layer fastening configurations

Compatibility

Designed as an OEM-style replacement or direct-install fastener for applications requiring a 7/8-9 UNC equal double threaded stud in alloy steel construction.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with fastener torque requirements for the specific assembly. Power down and de-energize any equipment before accessing fastener locations in mechanical systems. Use the flat feature with an appropriately sized wrench to thread into the base material before securing the mating nut on the exposed end. Follow applicable ASME or equipment manufacturer fastener specifications for final torque values.
