Keystone Threaded Products UM014AG1A002150 Hex Nut 7/8-6

Product Description

The KEYSTONE THREADED PRODUCTS UM014AG1A002150 is a right-hand Acme thread hex nut machined from steel for use in mechanical power transmission and linear motion assemblies. It is sized 7/8-6, meaning a 7/8-inch nominal thread diameter with 6 threads per inch, and conforms to the 2G Acme thread fit class. The width across flats measures 1-7/16 inches (1.4375 inches), and the nut stands 55/64 inches tall. Acme-threaded fasteners are common in lead screws, vises, jacks, and industrial positioning equipment. Machinists, millwrights, and maintenance technicians are the typical installers for this type of hardware.

This hex nut is suited for use in both original equipment and replacement applications involving Acme-threaded lead screws and rod ends. It is commonly installed in machine tools, industrial presses, linear actuators, and heavy fabrication jigs where controlled, load-bearing linear movement is required. The right-hand thread direction is the standard orientation for most Acme-thread assemblies. The steel construction provides the hardness and wear resistance expected in demanding mechanical environments.

Key Features

• 7/8-6 Acme thread specification with right-hand thread direction
• 2G thread fit class for standard commercial Acme thread applications
• Width across flats of 1-7/16 inches (1.4375 inches) for standard hex wrench engagement
• Height of 55/64 inches providing substantial nut engagement depth
• Steel construction for strength and wear resistance in mechanical drive applications
• Does not meet military specifications - suitable for commercial and industrial use

Compatibility

Designed for use with 7/8-6 right-hand Acme-threaded lead screws and rods in commercial and industrial mechanical assemblies. Verify thread pitch, fit class, and engagement length against your specific application before installation.

Installation Notes

This fastener is typically installed by machinists or maintenance technicians working on linear drive or power transmission equipment. Before servicing any assembly, de-energize the machine and relieve all mechanical load from the lead screw. Use a properly sized hex wrench or open-end wrench sized for 1-7/16 inch across flats. Inspect mating thread condition before installation to confirm the Acme thread profile and fit class are compatible.
