AMERICAN PRECISION TOOL & ENGINEERING, INC.

American Precision Tool & Engineering, Inc. specializes in the precision manufacturing of mission-critical mechanical components for defense applications, with deep expertise in ball and roller bearing systems and mechanical power transmission equipment. The company fabricates high-tolerance housings and structural parts designed for extreme operational environments, leveraging advanced CNC machining, metallurgical analysis, and tight-tolerance assembly techniques to meet military specifications. Their technical focus includes precision ground surfaces, hardened material compatibility, and vibration-dampening geometries critical to aerospace and armored vehicle drivetrain systems. What distinguishes their work is the consistent delivery of custom-engineered components where dimensional accuracy, material integrity, and repeatable performance are non-negotiable—often under stringent military drawing controls and inspection protocols. The contractor maintains a strong, sustained relationship with the Department of Defense, consistently delivering specialized mechanical components for propulsion, transmission, and rotating machinery subsystems across multiple service branches. Their work supports maintenance, repair, and overhaul programs for legacy and modernized platforms, indicating a trusted role in sustaining critical defense hardware through precision replacement parts. Industry focus centers on NAICS 332991 (ball and roller bearing manufacturing) and 333613 (mechanical power transmission equipment manufacturing), where they serve as a niche supplier of precision-engineered housings and assemblies for high-load, high-speed applications. This positions them as a specialized manufacturer within the defense industrial base, filling gaps in the supply chain for bespoke mechanical components that require exacting engineering controls beyond standard commercial production. As a small business operating from Pacoima, California, American Precision Tool & Engineering, Inc. is structured as a 2L entity with no federal certifications on record. Their geographic presence supports regional defense logistics networks, and their market positioning reflects a reliable, technically proficient supplier for specialized mechanical subsystems in defense systems requiring exacting manufacturing standards.
