Gibraltar 40770G Unequal Double Threaded Stud 1/2-13

Product Description

The GIBRALTAR 40770G is an unequal double threaded stud with a 1/2-13 thread size and an overall length of 1.5 inches. It is manufactured from Grade 5 carbon steel with a black oxide finish, offering moderate corrosion resistance and a non-reflective surface suited for industrial and mechanical assembly applications. Both the long and short thread lengths measure 5/8 inch, with a Class 50 thread fit. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors in equipment assembly, machinery mounting, and structural fastening situations where a stud rather than a standard bolt is required.

This stud is suited for use in general industrial, HVAC, plumbing, and mechanical system applications where a double-end threaded fastener is needed to join two components without a through-bolt. The unequal configuration, combined with a 1/2-13 coarse thread, makes it a practical choice for equipment panels, mounting brackets, and machinery frames in both commercial and light industrial settings.

Key Features

• 1/2-13 coarse thread size for broad compatibility with standard fastener hardware
• Overall length of 1.5 inches with equal long and short thread lengths of 5/8 inch each
• Grade 5 carbon steel construction for reliable tensile strength in mechanical applications
• Black oxide finish provides a non-reflective surface and mild corrosion resistance
• Class 50 thread fit for consistent engagement and secure holding power
• No flat, stud-style design intended for use with nuts on both ends

Compatibility

Designed as a standard unequal double threaded stud for use in mechanical assemblies, equipment mounting, and structural fastening applications requiring a 1/2-13 coarse thread fastener.

Installation Notes

Installation of double threaded studs is typically performed by millwrights, maintenance technicians, or mechanical contractors. Use an appropriate stud driver or two-nut method to thread the stud into the base material without damaging the threads. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or thread-locking compound as required by the application specification.
