Gibraltar 60553G Unequal Double Threaded Stud M12 X 1.75

Product Description

The GIBRALTAR 60553G is an unequal double threaded stud designed for bolted assemblies where two different thread engagement lengths are required at each end. Manufactured from carbon steel with a black oxide finish, this stud features an M12 x 1.75 thread form and an overall length of 80 mm. The long thread end measures 27 mm and the short thread end measures 16 mm, providing the asymmetric engagement common in mechanical and structural fastening applications. Material Grade 5 construction delivers reliable tensile strength for general industrial and trade use. Installation is performed by machinists, millwrights, and maintenance technicians working with threaded assemblies in equipment, fixtures, and fabricated structures.

This stud is suited for use in mechanical assemblies, equipment mounting, and structural connections where a continuous bolt is not practical and thread engagement depth must differ between the mating components. The Thread Fit Class 50 designation indicates a standard fit tolerance appropriate for most industrial applications. It is commonly used in manufacturing, maintenance, and repair operations across industrial and commercial settings.

Key Features

• Unequal thread lengths: 27 mm long end and 16 mm short end for asymmetric engagement
• M12 x 1.75 thread size for compatibility with standard metric fastener systems
• Carbon steel construction, Material Grade 5, for reliable tensile performance
• Black oxide finish provides mild corrosion resistance and reduces light glare on exposed hardware
• Thread Fit Class 50 for standard industrial tolerance fit
• No flat ground on shank, maintaining full round cross-section along the body

Compatibility

Designed as a standard-fit replacement or new-installation metric double threaded stud for industrial mechanical assemblies requiring M12 x 1.75 thread engagement on both ends with unequal thread lengths.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a stud driver or double-nut method to thread the short end into the tapped hole first. Ensure the receiving tapped hole is clean and free of debris before installation. Apply thread-locking compound or anti-seize as required by the application and manufacturer specifications. Always verify thread engagement depth meets the structural requirements of the assembly before applying load.
