Gibraltar 60556G Unequal Double Threaded Stud M12x1.75

Product Description

The GIBRALTAR 60556G is an unequal double threaded stud with an M12 x 1.75 thread form and a total overall length of 140 millimeters (approximately 5.51 inches). It is manufactured from carbon steel with a black oxide finish and carries a Thread Fit Class 50 rating and Material Grade 5. The long thread measures 39 millimeters (approximately 1.54 inches) and the short thread measures 16 millimeters (approximately 0.63 inches). This type of fastener is used to anchor components to a base surface on one end while accepting a nut or mating part on the opposite end. Installation is performed by maintenance technicians, millwrights, and general tradespeople across industrial and mechanical applications.

The 60556G suits applications requiring a permanent or semi-permanent threaded connection point in metal assemblies where a through-bolt is not practical. The unequal thread lengths allow one end to be driven into a tapped hole or pressed assembly while the exposed end provides a stud for component attachment. This fastener is appropriate for mechanical, industrial, and general manufacturing applications where carbon steel strength and a corrosion-inhibiting black oxide surface treatment are acceptable for the service environment.

Key Features

• Unequal double threaded design with a 39 mm long thread and 16 mm short thread for versatile anchoring configurations
• M12 x 1.75 thread form with Thread Fit Class 50 for consistent dimensional compliance
• Carbon steel construction at Material Grade 5 for reliable mechanical strength
• Black oxide finish provides a baseline level of corrosion resistance for indoor and protected environments
• No flat machined on body, maintaining full cylindrical shank profile
• 140 mm overall length (approximately 5.51 inches) covers common stud-mounting depth requirements

Compatibility

Designed as a standard M12 x 1.75 double threaded stud for use in metal assemblies and mechanical equipment requiring an unequal stud fastener with Thread Fit Class 50 and Material Grade 5 specifications.

Installation Notes

Installation is typically performed by qualified mechanical technicians or millwrights using appropriate torque tools sized for M12 fasteners. De-energize and lock out all equipment before fastener replacement or installation in powered mechanical assemblies. Verify that the receiving tapped hole is clean, properly sized, and free of damage before driving the stud to avoid cross-threading or galling. Follow applicable facility or equipment manufacturer torque guidance for M12 Grade 5 hardware; no specific torque value is specified for this part in the available product data.
