Gibraltar 60555G Unequal Double Threaded Stud M12 X 1.75

Product Description

The GIBRALTAR 60555G is an unequal double threaded stud with an M12 x 1.75 thread form and an overall length of approximately 4.33 inches (110 mm). It is manufactured from carbon steel with a black oxide finish and carries a Thread Fit Class 50 designation and Material Grade 5. The stud features two threaded ends of unequal length: a long thread of approximately 1.54 inches (39 mm) and a short thread of approximately 0.63 inches (16 mm), with an unthreaded shank in between. This fastener is installed by machinists, maintenance mechanics, and industrial assemblers in applications requiring a stud that threads into a tapped hole on one end and accepts a nut on the other.

The 60555G is suited for general industrial assembly, machine building, and maintenance and repair operations where a stud-and-nut fastening method is preferred over a bolt. The unequal thread lengths make it appropriate for applications where the stud must be anchored deeper into a component on one end while providing a shorter engagement length for a mating nut on the other. It is a common fastener choice in carbon steel construction where moderate corrosion resistance from a black oxide surface treatment is acceptable.

Key Features

• M12 x 1.75 thread form on both ends with unequal engagement lengths
• Long thread length of approximately 1.54 inches (39 mm) for deep tapped-hole engagement
• Short thread length of approximately 0.63 inches (16 mm) for nut-side fastening
• Carbon steel construction with Material Grade 5 for reliable tensile strength in industrial use
• Black oxide finish provides moderate surface protection and reduces light reflection
• Thread Fit Class 50 for consistent dimensional tolerance and fit

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for industrial assemblies, machine frames, and mechanical equipment requiring an M12 x 1.75 unequal double threaded stud in carbon steel.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a stud driver or double-nut method. Verify that the tapped receiving hole is clean and matches the M12 x 1.75 thread specification before driving the stud. Apply thread-locking compound or anti-seize as required by the application. Do not exceed the torque capacity appropriate for a Grade 5 carbon steel fastener in the given mating material.
