Gibraltar 23090.0012 M12x1.75 Coupling Nut Steel Din 6334

Product Description

The GIBRALTAR 23090.0012 is a standard coupling nut used to join or extend threaded rod and fastener assemblies. Made from Grade 10 steel with a black phosphate coating, this nut accepts M12x1.75 right-hand thread and measures 36 millimeters overall length. The black phosphate finish provides a base layer of corrosion resistance and improves lubricity during installation. With an 18 mm width across flats and a 20.8 mm width across points, the hex profile is compatible with standard metric wrenches and sockets. It meets DIN 6334 dimensional standards, making it a reliable choice for structural and mechanical fastening applications in trade and industrial work.

This coupling nut is suited for use in plumbing, HVAC, electrical, and general mechanical installations where threaded rod needs to be lengthened or two threaded fasteners need to be connected end-to-end. Typical applications include hanging pipe and conduit runs, mounting equipment to unistrut or threaded rod assemblies, and mechanical clamping fixtures. The M12x1.75 thread size is a common metric standard found in both light commercial and heavy mechanical environments. Tradespeople, maintenance technicians, and contractors working with metric fasteners will encounter this size regularly.

Key Features

• M12x1.75 right-hand thread for compatibility with standard metric threaded rod and fasteners
• Grade 10 steel construction for high tensile strength in demanding fastening applications
• Black phosphate coating provides corrosion resistance and reduces galling during installation
• 36 mm overall length (OAL) following DIN 6334 standard dimensions
• 18 mm width across flats fits standard metric wrenches and drive sockets

Compatibility

Designed as an OEM-style replacement and standard coupling nut for M12x1.75 metric threaded rod and fastener applications meeting DIN 6334 dimensional requirements.

Installation Notes

Installation is typically performed by mechanical, HVAC, plumbing, or electrical tradespeople using standard metric wrenches or sockets. Disengage and de-energize or depressurize any system before working on fastener assemblies in live mechanical or piping installations. Apply thread lubricant or anti-seize compound as appropriate for the service environment to prevent galling. Torque to the specification required by the specific application and governing code.
