Semiconductor Equipment
We are developing high-corrosion-resistance, high-precision fasteners for semiconductor manufacturing equipment.
What This Industry Requires
- Minimal particle generation
- High corrosion resistance — exposure to chemical atmospheres and cleaning processes
- Non-magnetic requirements (certain metrology and transfer equipment)
- Tight dimensional tolerance control
How We Respond
High-corrosion grade support
STS304Cu (A2) is our standard grade. For applications requiring higher corrosion resistance, we review your requirements and respond through individual consultation. The 316 series is demanding to cold-form — we approach it with half a century of cold-forming experience.
Precision dimensional control
Dimensions are controlled with an image dimension measuring system and profile projector, and we hold drawing data for every catalog item.
Magnetism consultation
Magnetism arising from cold working is not a pass/fail criterion under the standards, but applications requiring non-magnetic parts need separate review.
Main Products Supplied — Precision instrument screws, hex socket head cap screws, high-corrosion stainless machine screws
Cleanroom washing and packaging is not currently offered; we are reviewing its introduction. Tell us your requirements and we will advise what we can support.
