1.4mm High-Precision Male-Female Super Screw for PCB
The 1.4mm High-Precision Male-Female Super Screw is a two-in-one fastening element for printed circuit boards: the male thread on one end and the female thread in the head on the other let engineers space, stack and clamp boards with a single component instead of a screw, nut and standoff combination. Its 1.4mm envelope suits dense layouts where every fraction of a millimeter of board area and stack height counts.
Each screw is produced on high-efficiency deep-hole machining equipment from premium-grade alloy steel and finished with precision cold-rolled threads. Cold rolling forms the thread by displacing material instead of cutting it, so grain flow runs unbroken along the thread flanks. That produces a stronger, smoother, more fatigue-resistant thread — exactly what a joint needs when it is tightened, released and retightened thousands of times, or exposed to constant vibration in service.
Because the part carries both thread forms, the assembly gains fewer interfaces and fewer opportunities for loosening. Tolerances are held tight enough that the screw feeds reliably in automated equipment and picks up cleanly on the mating thread, protecting yield in high-volume SMT production lines.
Widely used in automotive powertrains, new-energy-vehicle chassis and battery electronics, industrial robotics and precision engineering, the 1.4mm super screw targets lightweight assemblies that must stay tight for the life of the product. Its small footprint combined with a fatigue-resistant joint makes it the practical choice where boards are stacked inside confined housings and serviced under continuous vibration.
It is also a natural fit for power modules, inverter control boards and sensor carriers, where a stable, repeatable threaded connection matters more than the cost of a few extra components.
