Left-Hand Thread Hexagon ACME Threaded Connector Nuts

SKU: N32 Categories: , ,

Left Hand Thread Hexagon ACME Threaded Connector Nuts, otherwise known as Hex Coupling Nuts or Extension Nuts, are used to combine two male threaded screws for the creation of a longer assembly.

Specifically designed for use with Left Hand Thread ACME Threaded Rods, they host a strong internal ACME thread and hexagonal shaped body – requiring a standard hex wrench for installation and removal.

These left-hand threaded nuts, sometimes called reverse threaded nuts, are driven in the opposite direction to conventional nuts. This can prevent self-loosening in certain situations whilst creating incompatibility with right-hand threaded components.

Featuring a 29° thread angle, the internal ACME thread is a strong symmetrical thread form to support heavy loads and allow higher torque to be achieved.

Left Hand Thread Hexagon ACME Threaded Connector Nuts are manufactured from Grade 2 Steel as standard. Other materials and finishes are available to order.

Available now with diameters from 1/2″ to 2″ as standard. Hexagon ACME Left Hand Threaded Nuts and right-hand threaded variants are also available at Fastenright, as well as a huge range of Threaded Rod.

Bespoke sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings – minimum order quantities apply.
