Gibraltar 23040.0123 Unequal Double Threaded Stud M12x1.75

Product Description

The GIBRALTAR 23040.0123 is an unequal double threaded stud manufactured from grade 10.9 alloy steel with a heat-treated finish. It features an M12 x 1.75 thread profile, an overall length of approximately 3.15 inches (80 mm), a long thread length of approximately 1.97 inches (50 mm), a short thread length of approximately 0.59 inches (15 mm), and an unthreaded shank length of approximately 0.59 inches (15 mm). The heat treatment and grade 10.9 rating deliver high tensile strength suited to demanding mechanical assemblies. This stud is installed by mechanics, maintenance technicians, and industrial assemblers wherever a reliable double-ended fastener is required.

This unequal double threaded stud is used in industrial and mechanical assembly applications where two different thread engagement lengths are needed on a single fastener. The longer thread end provides deeper engagement into a tapped housing or structural component, while the shorter thread end accepts a nut or mating part. Typical applications include machinery repair, equipment fabrication, and structural fastening in industrial maintenance environments. The DIN 787 thread fit class ensures dimensional conformance to recognized industry standards.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength
• Heat-treated steel finish for improved hardness and durability
• Unequal thread lengths: 50 mm long thread, 15 mm short thread
• 15 mm unthreaded shank between thread zones
• DIN 787 thread fit class for standardized dimensional conformance
• No flat — cylindrical shank profile throughout

Compatibility

Designed as a standard DIN 787 unequal double threaded stud for industrial and mechanical assembly applications requiring an M12 x 1.75 thread fastener with differing engagement lengths.

Installation Notes

Installation is performed by qualified mechanics or industrial maintenance technicians using appropriate thread engagement practices. Ensure tapped receiving holes meet the M12 x 1.75 thread specification and are free of debris before installation. Apply torque within the limits specified for grade 10.9 fasteners per applicable industry standards. Do not exceed rated torque or use the stud as a pry point, as this may compromise thread integrity.
