Gibraltar 40957G Unequal Double Threaded Stud 3/4-10 10 in

Product Description

The GIBRALTAR 40957G is an unequal double threaded stud designed for fastening applications that require different thread engagement lengths on each end. Manufactured from Grade 5 carbon steel with a black oxide finish, this stud measures 10 inches overall length with a 2.5-inch long thread on one end and a 0.875-inch short thread on the other. The 3/4-10 thread size conforms to standard unified coarse thread specifications, and the Class 50 thread fit provides a reliable, consistent engagement. It is installed by millwrights, maintenance technicians, and mechanical contractors working in industrial and commercial settings.

This stud is suited for structural and mechanical assemblies where a permanent or semi-permanent threaded connection is needed between two components, such as flanged joints, machinery bases, and equipment mounting applications. The unequal thread length configuration accommodates installations where one end requires deeper engagement into a tapped hole while the nut side requires a shorter thread projection.

Key Features

• Unequal thread lengths: 2.5-inch long end and 0.875-inch short end for versatile engagement depth
• 3/4-10 unified coarse thread for broad hardware compatibility
• Grade 5 carbon steel construction for reliable tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Class 50 thread fit ensures consistent thread engagement tolerances
• No flat ground — round shank profile throughout

Compatibility

Designed as a standard replacement or new-installation stud for mechanical assemblies requiring a 3/4-10 unequal double threaded stud with 10-inch overall length and Grade 5 carbon steel construction.

Installation Notes

Installation is typically performed by millwrights or mechanical technicians. De-energize and lock out all associated equipment before servicing any fastener connection. Use a stud driver or double-nut method to install — do not use pliers or pipe wrenches directly on the thread form. Verify tapped hole depth and thread condition before installation to ensure full thread engagement on the long end.
