Keystone Threaded Products UM010AG1A001550 Hex Nut 5/8-6

Product Description

The KEYSTONE THREADED PRODUCTS UM010AG1A001550 is a right-hand Acme thread hex nut with a 5/8-6 thread size and a 2G thread fit class. Made from steel, this nut is built for threaded fastening applications that call for Acme thread form, which is commonly used in linear motion, power transmission, and industrial assembly work. The width across flats measures 1-1/16 inches (1.0625 inches decimal), and the height is 39/64 inches. At 0.13 pounds, it is a compact, single-piece fastener suited for both light mechanical assemblies and heavier fabricated structures requiring reliable thread engagement.

This hex nut is used in industrial, mechanical, and trade applications where Acme thread fasteners are specified. The 5/8-6 Acme thread profile is common in lead screws, jack screws, vise mechanisms, and linear actuator assemblies found in manufacturing, HVAC equipment supports, and structural fabrication. Licensed tradespeople and industrial maintenance technicians typically install this fastener as part of threaded rod assemblies, machinery components, or custom bracket builds requiring a standard right-hand Acme thread engagement.

Key Features

• 5/8-6 Acme thread size with right-hand thread direction
• 2G thread fit class for standard Acme thread tolerance and clearance
• Steel construction for strength and durability in mechanical assemblies
• Width across flats: 1-1/16 inches (1.0625 inches) for standard hex wrench fitment
• Height: 39/64 inches - compact profile for tight assembly clearances
• Does not meet military specifications - intended for commercial and industrial use

Compatibility

Designed for use with 5/8-6 Acme right-hand threaded rods and lead screws in commercial and industrial mechanical assemblies requiring a 2G thread fit class.

Installation Notes

Install using a standard 1-1/16 inch hex wrench or open-end wrench. Ensure the mating threaded rod or lead screw also follows the Acme thread standard and right-hand thread direction before engagement. Verify thread fit class compatibility with the mating part prior to final assembly. Do not overtighten, as Acme thread nuts in power transmission applications are typically torqued to values specified by the equipment manufacturer.
