Cosmetic Screws

UNI-SHINE®
UNI-SHINE® is a proprietary texturing method which reveals the natural shine of stainless steel. Available in various unique patterns and textures to suit and match the fastener’s surroundings, this cosmetic finish gives a luxurious feel to any application and offers excellent durability.
Features & Benefits
- Available in various cuts
- Meets RoHS requirements
- Provides excellent resistance to wear and scratch
- Offers long lasting finish
UNI-COLOR®
UNI-COLOR® is a special color coating that is designed and formulated to meet high-end cosmetic needs and market trends. Available in both spray paint and physical vapor deposition (PVD) techniques, this environmentally-friendly cosmetic coating offers excellent coverage and resistance against wear and corrosion.
Spray Paint
Using polyurethane (PU) paint, this coating method offers consistent coverage on screw head with no limit to the range of colors that can be developed.
Features & Benefits
- Available in any Pantone color
- Uniform coating thickness
- RoHS compliance in both color coating and base material
- Resistance to wear and corrosion on color layer
Physical Vapor Deposition (PVD)
PVD is a vacuum coating process to produce a conformal metal-based thin film that can be uniformly deposited on electrically conductive surfaces. Using the sputtering method, a single coating layer provides ample coverage without modifying the surface profile. This technique is used in many electronic industries including optical media, optics and semiconductor components.
Features & Benefits
- Exceptional aesthetic finish
- Uniform coating thickness
- Superior resistance to wear and corrosion
- PVD coating has a high level of hardness
