Keystone Threaded Products NQ008AC2F001962 Precision Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NQ008AC2F001962 is a round precision Acme nut machined from bronze, designed for use in linear motion assemblies, feed screws, and positioning mechanisms that require a left-hand thread orientation. It features a 0.937-16 thread size with a 2C class of fit, a 1.12-inch overall length, and a 0.75-inch height. The 0.5-inch thread length and two-start thread configuration support efficient load transfer and smooth axial travel. This part is suited for mechanical assemblies where standard right-hand threading is not appropriate and where bronze construction provides corrosion resistance and self-lubricating properties.

This Acme nut is typically installed in industrial machinery, CNC equipment, manual positioning stages, valve actuators, and similar applications where a left-hand drive screw is part of the design. The bronze material makes it a practical choice in environments where galling resistance and moderate corrosion resistance are required. It is a single-piece hardware component ordered and packaged individually, making it suitable for both repair and new-build applications across light industrial and precision mechanical trades.

Key Features

• Left-hand thread orientation for assemblies requiring reverse-drive screw configuration
• 0.937-16 thread size with 2C class of fit for controlled clearance and smooth engagement
• Two-start thread design for faster linear travel per revolution
• Bronze construction provides corrosion resistance and natural lubricity
• Round body profile at 1.12 inches overall diameter for straightforward housing fitment
• Compact form factor: 1.12 inches long, 0.75 inches high, 0.5-inch thread length

Compatibility

Designed for use with 0.937-16 left-hand Acme lead screws in precision linear motion assemblies. Verify thread direction, thread starts, and class of fit against the mating screw before installation.

Installation Notes

Installation of this Acme nut should be performed by a qualified machinist or mechanical technician familiar with lead screw assembly. Power down and de-energize any associated drive system before removal or installation. Do not force-thread the nut onto the mating screw; confirm left-hand thread engagement before applying torque. Inspect the mating screw for wear or damage prior to installing a replacement nut.
