Keystone Threaded Products KL020AG1F182845 Threaded Rod

Product Description

The KEYSTONE THREADED PRODUCTS KL020AG1F182845 is a general-purpose ACME threaded rod machined from Grade C1018 low-carbon steel. It measures 6 feet in overall length and carries a 1-1/4-5 thread designation, meaning a 1-1/4 inch nominal diameter with 5 threads per inch. The thread is cut to a 2G fit class in a left-hand direction, following the general-purpose ACME standard. An oil finish provides basic corrosion protection during storage and handling. This rod is used in linear motion, clamping, and power-transmission assemblies where left-hand threading is required to prevent back-driving or to pair with opposing-thread mechanisms.

This threaded rod suits industrial, mechanical, and construction applications where a coarse-pitch ACME thread profile is specified. The left-hand thread direction makes it appropriate for turnbuckle assemblies, lead screw systems, and fixtures where a right-hand and left-hand pair must be used together. The 6-foot length allows field cutting to project-specific dimensions. Machinists, millwrights, maintenance technicians, and contractors working on structural or mechanical assemblies are the primary installers of this product.

Key Features

• 1-1/4-5 ACME thread profile: 1-1/4 inch nominal diameter, 5 threads per inch
• Left-hand thread direction for anti-back-drive and opposing-thread applications
• 2G fit class per general-purpose ACME threading standard
• Grade C1018 low-carbon steel construction for consistent machinability
• Oil finish applied for basic surface protection
• 6-foot length allows field cutting to required dimensions

Compatibility

Designed as a general-purpose ACME threaded rod for use in linear motion systems, turnbuckle assemblies, lead screw mechanisms, and structural applications requiring a 1-1/4-5 left-hand ACME thread profile.

Installation Notes

Use appropriate thread-cutting oil or lubricant when engaging mating nuts to avoid galling on the C1018 steel surface. Verify that all mating components are also left-hand threaded before assembly to prevent cross-threading or joint failure. Cut to length with a metal-cutting saw or cold saw, then clean and chamfer the cut end before use. Follow applicable mechanical and structural codes for fastener selection and joint design.
