RIDGE MACHINE SHOP INC

RIDGE MACHINE SHOP INC specializes in precision manufacturing of critical mechanical and electro-mechanical components for defense systems, with deep expertise in fastener production, gear systems, and propulsion unit parts. The company fabricates high-tolerance components including roller chains, split pins, cap screws, cams, and shims using advanced metal stamping, machining, and assembly techniques. Their technical capabilities span the full lifecycle of small-part manufacturing—from raw material processing to final inspection—ensuring compliance with stringent military specifications for durability, dimensional accuracy, and material integrity. Specializations include the production of industrial high-speed drives, pumping and measuring equipment components, and specialized fasteners used in guided missile systems, indicating a strong focus on mission-critical applications requiring repeatable precision and traceability. The contractor maintains an exclusive relationship with the Department of Defense, delivering components for aerospace, ordnance, and propulsion systems across multiple branches. Their work supports ground vehicles, missile guidance assemblies, and naval propulsion subsystems, with consistent demand for precision-engineered fasteners and mechanical linkages essential to operational readiness. This sustained engagement reflects a trusted role as a specialized supplier within the DoD’s industrial base, particularly for low-volume, high-complexity parts that require tight process control. Industry focus centers on NAICS 332722 (fastener manufacturing) and 336415 (propulsion unit parts), with additional strength in 333612 (industrial drives) and 333914 (pumping equipment). These categories reflect a niche positioning as a precision fabricator for defense-grade mechanical subsystems, serving both legacy and next-generation platforms requiring custom, non-standard components not produced at scale. RIDGE MACHINE SHOP INC is a small, privately held manufacturing firm based in Halifax, Pennsylvania, with no federal certifications listed. Operating as a Tier 2/3 supplier, the company leverages its localized machining capabilities to support defense supply chains requiring agile, responsive production of mission-critical hardware.
