Keystone Threaded Products UM012AG1A001845 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS UM012AG1A001845 is a 3/4-5 Acme thread hex nut machined from 1215/12L14 free-machining steel. It features a right-hand thread with a 2G fit class, making it suited for moderate-tolerance power transmission and linear motion assemblies. The nut measures 1.25 inches across flats and 47/64 inch in height, and weighs 0.193 pounds. It is installed by machinists, millwrights, and maintenance mechanics working on lead screw systems, conveyor drives, vises, and similar mechanical assemblies that rely on Acme thread profiles for controlled axial movement.

This hex nut is used in industrial and commercial maintenance applications where Acme thread forms are specified. Typical installations include lead screws on machine tools, linear actuators, jack screws, and feed mechanisms. The 2G fit class provides a standard running fit appropriate for general-purpose power transmission. The 1215/12L14 material grade offers good machinability and is commonly found in precision-machined fastener applications where moderate strength is acceptable.

Key Features

• 3/4-5 Acme thread size with right-hand thread direction
• 2G thread fit class for standard general-purpose running clearance
• 1215/12L14 free-machining steel construction
• 1.25 inches width across flats for standard wrench engagement
• 47/64 inch height suits compact axial space requirements
• Hex body allows installation and removal with standard open-end or box wrenches

Compatibility

Designed for use with 3/4-5 Acme threaded rod, lead screws, or shafts requiring a 2G fit class hex nut in steel construction.

Installation Notes

Installation is performed by machinists or maintenance mechanics using standard open-end, box-end, or socket wrenches sized for a 1.25-inch hex. De-energize and lock out all equipment before servicing any lead screw or linear actuator assembly. Verify thread engagement length and fit class compatibility with the mating lead screw before final assembly. Avoid applying excessive torque beyond what the 1215/12L14 material grade is rated to handle in the specific application.
