BETA SHIM CO.

BETA SHIM CO. specializes in the precision manufacturing of mission-critical metal components for aerospace and defense systems, with deep expertise in shim, spacer, washer, and liner production using high-tolerance machining and material-specific fabrication techniques. Their core capabilities center on custom hardware solutions for aircraft control systems, rotary hub assemblies, and structural interfaces, where dimensional accuracy and material integrity are paramount. The company excels in producing complex flat and profiled shims, retaining rings, and fastener components from aerospace-grade alloys, ensuring compliance with stringent military and aviation specifications. Their technical proficiency includes precision grinding, stamping, and heat treatment processes tailored to meet AS9100 and MIL-SPEC requirements, with a demonstrated focus on mission-critical interfaces that demand zero-defect reliability. The contractor maintains a consistent and long-standing relationship with the Department of Defense, supplying precision-engineered hardware for aircraft platforms, propulsion systems, and avionics assemblies. Their work supports sustainment, repair, and overhaul programs across naval, air force, and Army systems, where replaceable mechanical components must conform to exacting fit, form, and function standards. Industry focus is anchored in aircraft manufacturing (NAICS 336411) and hardware manufacturing (332510), with complementary strength in fastener and washer production (332722). This positions BETA SHIM CO. as a niche supplier of high-reliability mechanical interface components within the defense aerospace supply chain, serving integrators and Tier 1 contractors requiring certified, low-volume, high-precision parts. As a Women-Owned Small Business certified under the SBA’s WOSB program and operating from Shelton, Connecticut, the company leverages its small business status to provide agile, responsive manufacturing services to federal procurement channels. Their certification and geographic presence in a key Northeastern defense manufacturing corridor enhance their accessibility to defense logistics hubs and government inspection facilities.
