The KEYSTONE THREADED PRODUCTS KB006AC1I182880 is a 6-foot (72 inches) left-hand threaded rod machined to Precision ACME thread form with a 3/8-16 thread size and a 2C fit class. Manufactured from Grade B7 alloy steel, this rod is engineered for high-strength fastening applications where standard right-hand thread is not suitable. The single-start ACME thread profile provides reliable linear motion and load transfer. Grade B7 alloy steel delivers elevated tensile and yield strength compared to standard carbon steel fasteners, making it a go-to choice for structural, mechanical, and industrial assembly work.
This threaded rod is suited for applications requiring a left-hand thread orientation, such as assemblies where counter-rotation must be resisted or where opposing thread pairs are specified. Common uses include mechanical linkages, industrial machinery, construction bracing, HVAC equipment support structures, and utility installations where vibration or torque reversal could otherwise loosen a conventional right-hand fastener. Trade professionals in mechanical, plumbing, and HVAC disciplines regularly specify ACME-thread rods for actuator and lead-screw style assemblies in both commercial and industrial settings.
Designed as an OEM-style replacement or stock component for mechanical assemblies, structural supports, and industrial fastening systems that specify a 3/8-16 Precision ACME left-hand threaded rod in Grade B7 alloy steel.
Installation should be performed by a qualified mechanic, millwright, or licensed trade professional familiar with ACME-thread fastener systems. Shut down and de-energize any powered equipment before installing or replacing threaded rods in mechanical assemblies. Use appropriate thread-engagement depth and mating nut specifications to maintain rated load capacity. Left-hand thread engagement requires counter-clockwise rotation to tighten - confirm thread direction before installation to avoid cross-threading or assembly error.
