| Product Name | 1.4 mm PCB application thread class |
|---|---|
| Series | Precision Screws · PCB Application Series |
| Material | Quality alloy steel |
| Structure | Combined external and internal thread (inside/outside thread) |
| Key Process | Efficient deep-hole machining · precision thread rolling |
| Assembly Method | Suits automated assembly |
Overview
Micro precision screws are fasteners below roughly M2, cold-headed to tolerances where head geometry and recess depth are measured in fractions of a millimetre. At this scale the screw behaves as a controlled spring against a plastic or thin-metal boss, so preload must be specified as a band rather than a maximum. This listing: material Quality alloy steel.
What sets this listing apart: Key Process Efficient deep-hole machining · precision; Product Name 1.4 mm PCB application thread class.
Advantages
Tight recess-depth control lets automated drivers engage without cam-out at high cycle rates.
Plating thickness is held inside the recess tolerance so the driver still fits after coating.
Cold heading produces a continuous grain flow through the head-to-shank transition, which resists head shear far better than a machined micro screw.
Applications
Consumer electronics housings, wearable devices, camera modules, small appliance enclosures, and robot actuator assemblies.
Match the screw to the boss design: one size above the boss allowance cracks the plastic before torque is reached. Check the galvanic couple when the screw contacts a dissimilar metal.
