Gibraltar 40453G Unequal Double Threaded Stud 5/16-18 3 in

Product Description

The GIBRALTAR 40453G is an unequal double threaded stud with a 5/16-18 thread size and a 3 inch overall length. It features two threaded ends of different lengths: a long thread of 1.5 inches and a short thread of 0.5 inches, separated by an unthreaded shank. Manufactured from Grade 5 carbon steel with a black oxide finish, this stud provides corrosion resistance and surface hardness suitable for general industrial and mechanical fastening applications. It carries a Thread Fit Class 50 designation. Licensed tradespeople and maintenance technicians use this type of fastener to create secure, removable connections between two components where a bolt-through approach is not practical.

This unequal double threaded stud is suited for use in light industrial, mechanical, and general assembly applications where a fixed stud is needed to accept a nut on either end. The longer thread end is typically threaded into a tapped hole in a base component, while the shorter thread end accepts a nut to secure a mating part. It is a standard inch-series fastener appropriate for fabrication shops, maintenance facilities, and production assembly environments.

Key Features

• 5/16-18 UNC thread on both ends for compatibility with standard inch-series nuts and tapped holes
• Long thread length of 1.5 inches for deep engagement in base material
• Short thread length of 0.5 inches for nut retention on the exposed end
• Grade 5 carbon steel construction for reliable tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Thread Fit Class 50 for controlled thread tolerance and consistent fit

Compatibility

Designed for general use with standard 5/16-18 UNC tapped components and hex nuts in inch-series mechanical assemblies.

Installation Notes

Installation is performed by maintenance technicians or machinists using standard hand tools such as a stud driver or locking-nut method. Thread the long end fully into the tapped base component before securing the mating part with a nut on the short thread end. Always confirm the base material thread depth and condition before installation to ensure full thread engagement. Torque to the value specified in the applicable assembly drawing or engineering standard for 5/16-18 Grade 5 fasteners.
