Product overviewOverview

Physical vapour deposition builds the film in a vacuum chamber by evaporating or sputtering metal or ceramic onto the part. Appearance parts are accepted against the finished product colour, with the highlight position depending on how concentric the texture is. Heads are visible after assembly, so handling marks matter and packing is single-layer rather than bulk.

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

Key featuresFeatures

Colour matched to the product; concentricity checked separately.
Low-friction, hard film reduces galling during driving.
Film thickness 0.5–3 µm; thread gauging is identical to uncoated parts.
Vacuum deposition adds no hydrogen, avoiding a hydrogen-embrittlement risk.

Typical applicationsApplications

Premium audio faceplates
Optical and photographic equipment
Medical device housings, subject to cleaning validation

Selection notesSelection

PVD is a decorative and wear coating, not a corrosion system; for outdoor or salt-spray exposure specify a corrosion primer beneath the PVD.

Frequently asked questionsFAQ

Why are appearance screws packed in a single layer?

The PVD film is hard but brittle under impact, and bulk packing leaves dents on the visible face. Single-layer trays or foam dividers keep the head intact until assembly.

What matters during installation of the Hexalobular Socket Head PVD CD-Pattern Screw?

Drive it with an electric screwdriver, keeping the bit clear of the film. Colour matched to the product; concentricity checked separately.
