Gibraltar 23040.0163 Unequal Double Threaded Stud M16x2

Product Description

The GIBRALTAR 23040.0163 is an unequal double threaded stud designed for industrial fastening applications where two different thread engagement lengths are required on a single fastener. Manufactured from heat-treated alloy steel to material grade 8.8, this stud delivers high tensile strength and reliable clamping force. It features an M16 x 2 thread profile with an overall length of 100 millimeters. The long thread end measures 63 millimeters, the short thread end measures 19 millimeters, and an unthreaded shank section of 18 millimeters separates the two threaded zones. Thread fit conforms to DIN 787 class standards. Licensed trades and maintenance professionals specify this type of hardware in machinery assembly, structural connections, and equipment mounting.

This stud is suited for use in industrial and commercial mechanical assemblies where a fixed stud must engage a tapped hole on one end and accept a nut or coupling on the other. Typical applications include machine frames, flanged connections, and equipment bases requiring a permanent or semi-permanent threaded anchor point. The DIN 787 thread fit class makes this stud compatible with standard metric tooling and hardware commonly used in European-specification machinery and general industrial maintenance work.

Key Features

• Unequal thread lengths: 63 millimeter long end and 19 millimeter short end for asymmetric engagement
• M16 x 2 metric thread profile conforming to DIN 787 fit class
• Heat-treated alloy steel construction at material grade 8.8 for high tensile strength
• 18 millimeter unthreaded shank between thread zones
• No flat on shank, keeping the profile clean for close-clearance installations
• UNSPSC Code 31161618 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or direct-fit stud for industrial machinery and mechanical assemblies requiring an M16 x 2 DIN 787 class double threaded fastener.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener standards. Shut down and de-energize all associated equipment before removing or installing studs in live machinery. Use a proper stud driver or double-nut method to install without damaging threads. Verify that the tapped receiving hole is clean, properly sized for M16 x 2 thread engagement, and free of debris before driving the stud.
