Accurate Screw Machine

What Accurate Screw Machine does

Accurate Screw Machine (ASM) is a US-based manufacturer of precision fasteners and custom-machined components serving aerospace, defense, and industrial end markets. Founded in 1967 and operating today as a division of MW Components (itself part of MW Industries), ASM produces a broad catalog that includes NAS/MS/AN specification hardware, screws, spacers, standoffs, washers, bushings, captive screws, captive screw assemblies (SEMs), nuts, studs, locking fasteners, handles, ferrules, and retainers. The company is AS9100D and ISO 9001:2015 certified and holds CAGE Code 51506, qualifying it as an approved supplier for government and defense procurement. Manufacturing is grounded in precision CNC and screw-machine production across metric and standard sizes, with capabilities spanning stainless steel, super alloys, and exotic metals, plus in-house finishing services such as anodizing, black oxide, cadmium, and nickel plating.

ASM operates a hybrid commercial model. Standard in-stock parts—now including more than 90 NAS/MS/AN part numbers—are sold through a self-serve e-commerce storefront with same-day or 24-hour shipping and flexible low minimum order quantities. Modified and bespoke components are sold via direct sales engagement (phone, email, quote requests) with lead times starting at four weeks and expedited options available, supported by in-house design-for-manufacturability engineering and custom CAD generation. The company markets primarily through the MW Components corporate website, SEO, and direct outreach rather than field sales at scale. ASM's competitive position is anchored in regulatory certifications, qualified-supplier status in aerospace and defense, and a stocking model that delivers faster availability than competitors reliant on longer production runs.
