For design engineers optimising assembly integrity, EJOT’s Industrial Engineering range delivers precision-engineered fastening solutions tailored for demanding applications. The product offering spans a highly versatile selection of geometry profiles, including standard and micro-sizes like the m5 countersunk screw and m3 countersunk screw. For flush surface finishes or specific geometric nesting, EJOT provides exceptionally engineered raised head countersunk screws and raised countersunk screws, alongside specialised countersunk anchors and countersunk fasteners that distribute clamping loads evenly without compromising material aesthetics.
When high torque transmission and integrated load distribution are paramount, EJOT’s portfolio excels with high-performance drive configurations. This includes the flanged hex screw, hex flange screw, and flanged hex head screws, which eliminate the need for separate washers, reducing part counts and assembly time. For heavy-duty framing or sheet metal work, the hex washer head screw and hex washer head self-drilling screw offer superb pull-out resistance and rapid installation.
Engineers can also leverage their extensive selection of hexagon fasteners, pan head fasteners, and precise torx flange head screws or torx flanged button screws for superior cam-out resistance during automated assembly. Each raised countersunk head and raised countersunk head screw is optimised to minimise stress concentrations in the host material.
Advanced Coating Benefits
To ensure long-term reliability in corrosive or high-wear environments, EJOT pairs these geometries with advanced zinc-flake and organic surface coatings.

- Corrosion Resistance: High-grade zinc-flake coatings provide exceptional chemical and galvanic corrosion protection, easily surpassing 1,000 hours in salt spray testing without inducing hydrogen embrittlement.
- Controlled Friction: Integrated topcoats offer a predictable friction coefficient, crucial for achieving exact clamping forces under automated tightening torque.
- Material Compatibility: Specialised coatings act as a barrier layer, preventing galvanic corrosion when steel fasteners are driven into aluminium or lightweight magnesium alloys.
