Gibraltar 60651G Unequal Double Threaded Stud M16x2 80mm

Product Description

The GIBRALTAR 60651G is an unequal double threaded stud with an M16 x 2 thread form and an 80 mm overall length. It is manufactured from carbon steel with a black oxide finish and rated at Thread Fit Class 50. The long thread measures 21 mm and the short thread measures 18 mm, making the two ends intentionally asymmetric for applications where different engagement depths are required. This type of stud is commonly installed by millwrights, maintenance mechanics, and assembly technicians in industrial and mechanical fabrication settings where bolted joint integrity is critical.

This stud is suited for use in industrial machinery, equipment assemblies, and structural mechanical connections where a fixed, non-rotating threaded fastener is needed. The black oxide finish provides a low-reflectivity surface and modest corrosion resistance in dry or lightly oiled environments. Applications include mounting flanges, bearing housings, and mechanical sub-assemblies that require reliable, repeatable thread engagement on both ends.

Key Features

• M16 x 2 thread size on both ends with unequal thread lengths for asymmetric engagement
• Long thread length of 21 mm and short thread length of 18 mm
• 80 mm overall length provides versatile fastening reach
• Carbon steel construction with Material Grade 5 for dependable tensile strength
• Black oxide finish for low-glare appearance and light corrosion resistance
• Thread Fit Class 50 ensures consistent dimensional tolerance compliance

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial mechanical assemblies requiring an M16 x 2 unequal double threaded stud with an 80 mm overall length and Class 50 thread fit.

Installation Notes

Installation is typically performed by qualified millwrights or mechanical technicians using standard metric tooling. Ensure the mating threaded bore is clean and free of debris before driving the short-thread end into the fixed component. Apply appropriate thread lubricant or locking compound per the equipment manufacturer's specification. Verify proper thread engagement depth on both ends before applying final torque to the nut or mating fastener.
