Gibraltar 40951G Unequal Double Threaded Stud 3/4-10 4 in

Product Description

The GIBRALTAR 40951G is an unequal double threaded stud designed for fastening applications that require two different thread engagement lengths on a single fastener. Manufactured from Grade 5 carbon steel with a black oxide finish, this stud measures 4 inches overall and features a 1-3/4 inch long thread on one end and a 7/8 inch short thread on the opposite end. The Thread Fit Class 50 designation ensures controlled interference or transition fit performance. Electricians, plumbers, HVAC installers, and general trade mechanics use double threaded studs where a bolt cannot be inserted from one side or where permanent installation into a tapped hole is required.

This stud is suited for use in mechanical assemblies, equipment mounting, and structural fastening applications across residential and commercial trade work. The unequal thread length configuration makes it particularly useful when one end requires deeper engagement into a base material while the other end accepts a nut for clamping. It is a common component in HVAC equipment mounting, pipe support hardware, and electrical panel or enclosure assemblies where stud-mount fastening is standard practice.

Key Features

• Unequal thread lengths: 1-3/4 inch long end and 7/8 inch short end on a single 4-inch stud
• 3/4-10 UNC thread size for heavy-duty fastening applications
• Grade 5 carbon steel construction for strength in structural and mechanical installs
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread Fit Class 50 for controlled fit in tapped holes
• No flat machined on body, maintaining full cylindrical shank

Compatibility

Designed as a general-purpose double threaded stud for use in any assembly requiring a 3/4-10 UNC threaded interface with unequal engagement lengths on opposing ends.

Installation Notes

Installation is typically performed by mechanics, millwrights, or trade professionals using a stud driver or double-nut method to thread the long end into the tapped base material first. De-energize and de-pressurize any system before installing or removing fasteners in live equipment. Ensure the receiving tapped hole is clean and free of debris before driving the stud. Follow applicable torque specifications from the equipment manufacturer or governing code for the assembly type.
