Value Collection 621050PS M12x1.75 Coupling Nut 36mm

Product Description

The VALUE COLLECTION 621050PS is a standard metric coarse coupling nut used to join or extend threaded rod, all-thread, and bolt assemblies with an M12x1.75 thread. Made from steel with a zinc-plated finish for basic corrosion resistance, this coupling nut meets DIN 6334 dimensional standards. It measures 36mm in overall length with a 19mm width across flats, making it compatible with standard hex tooling. Machinists, pipefitters, millwrights, electricians, and general maintenance trades use coupling nuts like this when connecting threaded rods or extending bolt reach in structural and mechanical assemblies.

This coupling nut is suited for light industrial, mechanical, and construction applications where metric threaded rod or bolt extension is required. The right-hand M12x1.75 thread pitch is the standard coarse designation for M12 fasteners, meaning it mates with the most common M12 threaded hardware encountered in equipment assembly, strut channel work, and suspended system installations. The zinc coating provides a baseline level of moisture resistance appropriate for indoor or sheltered environments.

Key Features

• M12x1.75 metric coarse right-hand thread for compatibility with standard M12 hardware
• Steel construction with zinc-plated finish for basic corrosion resistance
• 36mm overall length provides extended thread engagement for rod joining or extension
• 19mm width across flats fits standard metric hex wrenches and sockets
• Meets DIN 6334 dimensional standard for metric coupling nuts

Compatibility

Designed for use with M12x1.75 metric coarse right-hand threaded rod, all-thread bar, and bolts conforming to standard metric fastener specifications.

Installation Notes

Installation requires a standard metric hex wrench or socket sized for 19mm across flats. Ensure mating threaded rod or fasteners are also M12x1.75 right-hand thread before assembly. In structural or load-bearing applications, follow applicable mechanical or building codes for fastener torque and engagement requirements. Inspect zinc coating for damage before use in moisture-exposed environments, as damaged plating will reduce corrosion resistance.
