Gibraltar 41058G Unequal Double Threaded Stud 7/8-9 12 in

Product Description

The GIBRALTAR 41058G is an unequal double threaded stud with a 7/8-9 thread size and a 12-inch overall length. It features two distinct threaded sections: a long thread measuring 3 inches and a short thread measuring 1.25 inches, with the remaining shank left unthreaded between them. Manufactured from Grade 5 carbon steel with a black oxide finish, it delivers solid corrosion resistance and mechanical strength suitable for demanding fastening applications. The Class 5 thread fit ensures proper engagement and holding force. This stud is installed by machinists, millwrights, maintenance technicians, and mechanical contractors in industrial and structural assemblies.

Unequal double threaded studs like the 41058G are used where two different thread engagement lengths are required at opposite ends of a single fastener. Common applications include machinery mounting, equipment bases, flanged connections, and structural bolted assemblies in industrial, commercial, and trade service environments. The unequal thread configuration allows one end to be permanently set into a tapped hole while the opposite end accepts a nut for clamping or adjustment.

Key Features

• 7/8-9 thread size with Class 5 thread fit for secure, consistent engagement
• 12-inch overall length with a 3-inch long thread and a 1.25-inch short thread
• Grade 5 carbon steel construction for high tensile strength
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• No flat ground on shank, maintaining full cylindrical profile
• UNSPSC Code 31161618 for procurement and catalog classification

Compatibility

Designed as a standard unequal double threaded stud for use in any tapped hole or mechanical assembly requiring a 7/8-9 thread form and a 12-inch overall stud length.

Installation Notes

Installation is typically performed by millwrights, machinists, or maintenance mechanics using a stud driver or double-nut method. Power down and de-energize all equipment before servicing any fastened assembly. Thread engagement depth into tapped holes should meet minimum engagement requirements per applicable engineering or code standards. Do not exceed the rated load capacity of the stud or the tapped material.
