Gibraltar 40454G Unequal Double Threaded Stud 5/16-18 4 in

Product Description

The GIBRALTAR 40454G is an unequal double threaded stud with a 5/16-18 thread size and a 4-inch overall length. Double threaded studs feature threads on both ends of an unthreaded shank, and this unequal version provides two different thread engagement lengths on each end. The long thread end measures 1.5 inches and the short thread end measures 0.5 inches. Constructed from Grade 5 carbon steel with a black oxide finish, this stud delivers solid mechanical strength and basic corrosion resistance in typical fastening applications. It is installed by tradespeople and maintenance technicians requiring reliable threaded fasteners for mechanical assemblies.

This stud is suited for use in a wide range of industrial, mechanical, and trade applications where a fixed threaded anchor point is needed in a housing, plate, or structural member. The unequal thread lengths allow one end to be permanently threaded into a tapped hole while the other end accepts a nut, bracket, or component for repeated assembly and removal. Typical install environments include equipment panels, HVAC component brackets, electrical enclosures, and general mechanical assemblies that call for a Class 50 thread fit.

Key Features

• Unequal thread configuration: 1.5-inch long thread end and 0.5-inch short thread end
• 5/16-18 UNC thread size with Class 50 thread fit for consistent engagement tolerances
• Grade 5 carbon steel construction for reliable tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 4-inch overall length accommodates deeper panel or housing engagement requirements
• No flat on shank, maintaining a clean cylindrical profile across the grip area

Compatibility

Designed as an OEM-style replacement or direct-use fastener for mechanical assemblies requiring a 5/16-18 unequal double threaded stud with a 4-inch overall length and Class 50 thread fit.

Installation Notes

Installation is performed by qualified technicians or tradespeople using standard hand tools including an appropriate wrench or stud driver for 5/16-18 thread engagement. The long thread end is typically threaded fully into the tapped base material before attaching components to the short thread end. Ensure tapped hole depth and thread condition are verified before installation to maintain proper Class 50 fit. De-energize and isolate any equipment before installing or removing fasteners in live assemblies.
