Need RoHS-Compliant Fasteners with Enhanced Vibration Resistance for Electronics Assembly?

Our trivalent chromium zinc plated hex washer head screws with serration under the head provide RoHS-compliant coating and superior anti-loosening performance for electronic equipment assembly. The 5μm coating thickness ensures corrosion resistance while the serration creates increased friction to prevent loosening in high-vibration environments. Contact us for coat inspection reports and custom specifications tailored to your electronics manufacturing requirements.

With comprehensive measurement protocols using calipers, protrusion-height gauges, micrometers, and 2.5D/2D projectors, we verify critical dimensions including hex flat and corner measurements, head height, slot specifications, serration count, thread parameters (length, major/minor diameter, angle, pitch), and coating thickness. Our inspection process includes ring gauge GO/NO GO testing and complete coat inspection with detailed reports provided. This meticulous quality control ensures that each #10-24*5/8 fastener meets exact specifications, delivering reliable performance for OEM manufacturers requiring precision coating screws with superior corrosion resistance and assembly integrity.
