Micro Screws

For design engineers working on the cutting edge of miniaturisation, component joining presents a unique set of structural challenges. As devices in consumer electronics, medical technology, and automotive sensors shrink, the demand for highly reliable, scaled-down fastening solutions becomes critical. EJOT’s Industrial Engineering range directly addresses this need with a comprehensive portfolio of high-performance micro screws.

At the core of this specialised range are micro self-tapping screws, engineered to provide secure, stress-free joints in plastics and light alloys without the need for pre-tapped threads. By utilising advanced thread geometries like the DELTA PT® and ALtracs® Plus configurations in miniature sizes, these fasteners optimise material displacement. This significantly reduces radial stress on delicate bosses while maximising clamp load and strip-out resistance, ensuring long-term joint integrity in compact assemblies.

To combat the installation risks inherent to micro-assembly, such as cam-out, driver slippage, and stripped heads, EJOT integrates high-precision drive systems across the range. The inclusion of small torx screws (and TORX PLUS® variants) ensures optimal torque transfer and precise axial alignment during automation or manual assembly. This specialised drive interface minimises tool wear and guarantees a repeatable, controlled tightening process, which is essential for high-volume production lines where component failure is not an option.

EJOT’s Industrial Engineering support extends beyond standard catalogue items. Design engineers benefit from comprehensive technical application analysis, including torque calculations and material testing, to tailor the fastener perfectly to the application. By choosing EJOT's miniature fastening technology, engineers can confidently push the boundaries of compact product design, achieving significant weight reduction and space savings without compromising on mechanical strength or assembly efficiency.
