What KAMAX does

KAMAX Holding GmbH & Co. KG is a privately held, family-owned German manufacturer of high-strength fasteners and complex cold-formed parts, founded in 1935 and headquartered in Homberg (Ohm), Germany. The company operates approximately 15 production sites across Europe and Asia (Germany, Spain, Poland, Slovakia, Czech Republic, Turkey, China) plus US operations in Michigan, employing roughly 3,000 people. Its core technology is cold forming and cold heading, enabling the production of ultra-high-strength fasteners with tensile strengths from 1,200 to 1,700 MPa, with proprietary innovations branded under the KX prefix (e.g., KXtreme, KXprotect, KXgreen, KXhead, KXact, KXfit) that address hydrogen resistance, corrosion protection, weight reduction, tight preload tolerances, and sustainable manufacturing without conventional heat treatment.

KAMAX serves primarily Tier-1 automotive OEMs and EV manufacturers, producing application-specific screws, formed parts, precision parts, and pre-assembled construction groups for vehicle systems including engine, drivetrain, wheels, suspension, seating, brakes, steering, body, electrical systems, and exhaust. Key named customers include Maruti Suzuki, Toyota, Volkswagen, General Motors, Hyundai, and FCA/Stellantis. The company operates a direct B2B enterprise sales motion, co-developing bespoke fasteners alongside customer engineering teams, with revenue generated through hardware sales on negotiated per-project contracts. It holds IATF 16949 automotive quality certification, ISO 9001, ISO 14001 (with EMAS registration), and ISO 45001 across its manufacturing sites.

The business model is anchored by a 100%-owned tooling subsidiary (KAMAX Tools & Equipment, 200+ employees) that produces custom automated tooling in-house, plus an online fastener platform (4fastening) and the Robert Schröder partner brand. On April 10, 2026, KAMAX signed a definitive agreement to be acquired by Italian fastener manufacturer Fontana Gruppo, a transaction pending regulatory approval that would create a combined entity of 42 manufacturing facilities, 9,000+ employees, and approximately two billion euros in revenue.
