The KEYSTONE THREADED PRODUCTS KB012AC1D182850 is a precision ACME threaded rod designed for high-load fastening and power-transmission applications in industrial, mechanical, and structural assemblies. It features a 3/4-6 thread size with a single-start, right-hand ACME thread profile and a 2C fit class, which provides the controlled clearance required for smooth linear motion and reliable engagement under load. The rod is machined from Grade B7 alloy steel, a chromium-molybdenum material known for its high tensile strength and resistance to elevated temperatures. At 6 feet in length and 6.87 pounds, it suits both shop fabrication and field installation work.
This threaded rod is used in applications requiring precise linear actuation, clamping, or mechanical advantage. ACME threads are commonly specified over standard V-threads in lead screw assemblies, jacking systems, vises, presses, and valve stems because of their superior load-carrying profile. Grade B7 alloy steel makes this rod appropriate for high-stress environments, including industrial machinery, structural support systems, and process equipment where elevated torque and temperature resistance are requirements. Machinists, millwrights, pipefitters, and industrial mechanics are the typical trades working with this type of fastener stock.
Designed as a standard precision ACME threaded rod for use in lead screw assemblies, jacking mechanisms, and industrial fastening applications where a 3/4-6 2C ACME thread specification is required.
Installation of threaded rod in structural or mechanical assemblies should be performed by a qualified millwright, pipefitter, or mechanical technician familiar with applicable load and torque requirements. Cut rod to length using appropriate metal-cutting equipment and deburr cut ends before threading nuts or flanges. Always verify thread fit and class compatibility with mating components before final assembly. Follow applicable ASME or facility-specific mechanical codes when using threaded rod in pressure-bearing or structural support applications.
