Keystone Threaded Products US010AG1A001560 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS US010AG1A001560 is a 5/8-8 Acme thread hex nut machined from Grade 303 stainless steel. It features a right-hand thread with a 2G fit class, making it suitable for power transmission and linear motion applications where corrosion resistance is required. The nut measures 1-1/16 inches across flats and 39/64 inches in height, conforming to standard Acme thread geometry. At 0.119 pounds, it is a compact, single-piece fastener installed by mechanics, millwrights, and maintenance technicians working on threaded rod assemblies, lead screws, and similar mechanical systems.

This hex nut is suited for use in industrial, commercial, and light manufacturing environments where Acme-threaded fasteners are specified. The 303 stainless steel construction provides good machinability and resistance to atmospheric corrosion, making it appropriate for applications that see moisture or mild chemical exposure. It is commonly used in fabricated frames, positioning stages, valve stems, and other assemblies that rely on Acme thread profiles for controlled linear movement.

Key Features

• 5/8-8 Acme thread profile with right-hand thread direction
• Grade 303 stainless steel for corrosion resistance and machinability
• 2G thread fit class for standard commercial-grade engagement
• 1-1/16 inches across flats for use with standard hex tooling
• 39/64 inches height for compact stack-up in threaded assemblies

Compatibility

Designed as an Acme thread hex nut for use with 5/8-8 Acme-threaded rod, lead screws, or spindles in mechanical assemblies requiring a 2G fit class.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using an appropriately sized open-end or combination wrench sized for a 1-1/16 inch hex. Verify thread engagement and fit class match the mating Acme-threaded component before final assembly. De-energize and lock out any powered equipment before servicing assemblies that incorporate this fastener. Do not force-thread onto mismatched thread profiles, as this can damage both the nut and mating component.
