What EJOT ATF makes

EJOT ATF, long known as Accurate Threaded Fasteners, designs and manufactures cold-formed and machined metal components, assemblies, and engineered fasteners for complex, safety-critical applications. Cold forming is the core competency, supported by machining, stamping, roll forming, assembly, and in-house tool and die work. The company points and shaves, drills, and broaches headed blanks and bar stock to reach shapes and tolerances that cold forming alone cannot hold, and its stamping presses run from 9 to 450 tons to flatten, bend, pierce, trim, and tap cold-formed blanks.

Its best-known product line is thread-forming fasteners for plastics and light metals. EJOT ATF is the first EJOT DELTA PT licensee in North America and describes itself as the largest DELTA PT licensee in the world. The catalog also includes the EVO PT self-tapping screw for thermoplastics and thermosets, the newer TOBI Drive System, cold-formed specials, ball studs used in gas-spring pivots and headlamp adjustment, and seat-belt anchors. Applications span automotive braking, chassis, engines, drive systems, and powertrains, along with aerospace, electronics, and lighting. Manufacturers across North America use the company's application-engineering support to design the joint, and its A2LA-accredited laboratory runs drive torque, stripping torque, clamp-load-under-temperature, pull-out, and tensile testing to validate parts in the customer's exact OEM or tier-supplier application.

Ownership and history

Accurate Threaded Fasteners was established in Lincolnwood, Illinois in 1946 and grew into a privately held designer and manufacturer of specialty fasteners and cold-formed components, reporting roughly $50 million in annual sales by the mid-2010s. In August 2023, EJOT and ATF, described in the announcement as long-standing joint-venture partners, realigned their North American industrial-fastener activities. Under the "EJOT 2025" strategy, they formed a new joint venture, EJOT ATF LP, in which the German EJOT Group holds a 51 percent majority. The North American business of EJOT's Market Unit Industry and the ATF business were merged into the venture, and EJOT also took majority control of the existing EJOT ATF Fasteners de Mexico operation in San Luis Potosi. EJOT Group is a family-owned fastening-technology company headquartered in Germany that serves construction, engineering, automotive, and consumer-electronics markets.

The combined company keeps its headquarters at 3550 W. Pratt Ave. in Lincolnwood, north of Chicago, with two Michigan plants near Detroit at Romulus and Rose City and the Fasteners de Mexico plant in San Luis Potosi. Kevin Brennan was appointed president in 2015, per the company's own announcement, joining from micro-precision manufacturer Mikrotech after earlier building ASYST Technologies, an EJOT/ATF automotive-lighting joint venture, over fourteen years. The company describes itself as family-run and organized around a set of values it calls The ATF Way.

Certifications and quality

EJOT ATF states that it holds IATF 16949:2016 certification, achieved in August 2018 across its Lincolnwood, Romulus, and Rose City facilities, along with ISO 14001 environmental management and an A2LA-accredited metrology laboratory. Its quality and process engineering group manages audits and certifications and works to root-cause customer issues rather than screen for them after the fact. Sustaining engineers use finite element analysis to assess manufacturability and how parts form during production, part of a PPAP-oriented discipline expected of automotive fastener suppliers.

Known customers

Most of EJOT ATF's customer relationships are unnamed, as is normal for a fastener and cold-forming supplier serving OEM and tier programs. One relationship is on the public record through a supplier award.

Beyond that, the company describes itself as a supplier to automotive OEMs and Tier 1 and Tier 2 suppliers, with cold-formed and machined parts used in braking, chassis, powertrain, aerospace, electronics, and lighting applications. Those are sector claims, not named-account claims.
