What K-J Fasteners does

K-J Fasteners Inc. is a privately held, US-based specialty fastener manufacturer founded in 1975 by Don "Stoney" Stonebrook and headquartered in Mentor, Ohio. The company operates three Strategic Business Units: a captive manufacturing facility, sourcing of special fasteners and OEM replacement components, and a kitting/assemblies operation. Core products include custom fasteners manufactured to customer prints, OEM replacement components, CNC-machined threaded fasteners and industrial components, and value-added kits and assemblies. Material capability spans commodity through exotic alloys (Inconel, Hastelloy, Titanium, Monel, Duplex, composites), with secondary services such as deburring, forming, bending, laser cutting, welding, heat treating, plating, and grinding delivered through long-standing vendor partnerships.

Revenue is generated through a quote-based, project-by-project B2B sales model targeting two primary customer segments: OEMs requiring application-oriented components and distributors seeking broad-range specialty fastener sourcing. Pricing is not publicly disclosed; customers submit specifications via website forms, phone, or email and receive itemized quotes covering pricing, lead times, and ancillary services. The company supplements transactional orders with recurring just-in-time inventory programs designed to reduce customer carrying costs. Marketing is concentrated on a company website with quote functionality, an active LinkedIn presence, and direct sales engagement; no channel partners or resellers are used. The business is supported by an ISO 9001-2015 certified quality management system (re-certified through 2027 by Smithers) and has been recognized eight times with the Fast Track 50 Award and inducted into its Hall of Fame.
