❓ Frequently Asked Questions About Our PVD Coated 304 Stainless Steel Flat Washers
🎨 How durable is the PVD colored coating?
The PVD vacuum coating delivers bright, fade-resistant color and greatly boosts surface hardness. It provides far better wear and anti-corrosion performance than ordinary paint plating, suitable for long-term outdoor vehicle use. Please avoid sharp hard objects scratching the coating surface to maintain perfect appearance.
🌧️ Can these washers be used in wet outdoor environments?
Absolutely. Made of solid 304 stainless steel with extra PVD protective coating, the washers feature strong rust and oxidation resistance. They work stably on motorcycles, e-bikes and other outdoor equipment without rusting easily under rain or humid conditions.
📏 What metric sizes are offered for these flat washers?
We supply 5 common metric sizes covering M4, M5, M6, M8 and M10 with matched outer diameter and thickness specs. Select the exact size matching your bolt thread before checkout to ensure perfect fitting for your modification projects.
🏍️ Where can these colored washers be installed?
Widely used for motorcycle engine covers, fuel tanks, handguards and body fairings; e-bike frames, disc brake rotors and motor mounts; PC water cooling brackets and PSU fixing; automotive interior/exterior trim fasteners and general mechanical anti-rust decorative spacers.
🔧 Installation tips for the stainless steel flat washers?
Slide the washer onto the bolt and attach it closely against the component surface, then fasten the nut or fitting. Tighten according to standard torque specs: M4 ~2.5N·m, M6 8-10N·m, M10 30-35N·m. This evenly distributes clamping force and avoids part damage from over-tightening.
⚠️ Are these flat washers anti-loosening for vibrating parts?
Flat washers only disperse pressure and do not own the locking function of spring lock washers. For high-vibration positions such as motorcycle engines, please use together with lock nuts or spring washers to prevent loosening during operation.
