Product overviewOverview

Because the film is only microns thick, the pitch diameter of an M2 thread is effectively unchanged and the part can be supplied to the original thread tolerance. Wear resistance comes from hardness — nitride films commonly exceed 1500 HV — but impact resistance is lower than a plated layer, so the driver bit should not be allowed to chatter against the head.

installed by electric driver, avoiding tip contact with the film.

Key featuresFeatures

Gunmetal, black, gold and blue finishes with controlled colour difference within a lot.
CD pattern on the head gives a concentric reflection used for cosmetic identification.
Low-friction, hard film reduces galling during driving.
Film thickness 0.5–3 µm; thread gauging is identical to uncoated parts.

Typical applicationsApplications

Smartwatch case and strap attachments
Premium audio faceplates
Optical and photographic equipment

Selection notesSelection

Use a bit with controlled magnetic force to avoid scratching the film and exposing the substrate.

Manufacturing and inspection

Colour is checked against a master plaque with a spectrophotometer, with ΔE held inside the agreed window.Alternative materials and finishes can be quoted side by side during sampling, so cost and corrosion resistance can be traded off explicitly.
