How Can You Reduce Assembly Time While Ensuring Consistent Electrical Grounding in High-Volume Production?

Our pan head SEMS screws with integrated rolling serration washers eliminate separate washer handling, reducing assembly steps by 50% while the serrated washer teeth penetrate surface oxidation to ensure reliable electrical continuity. ISO-compliant inspection of all critical dimensions guarantees consistent performance across millions of units. Contact us for samples tested to your specific grounding requirements.

With 45 years of fastener manufacturing expertise, we utilize precision inspection tools including calipers, protrusion-height gages, micrometers, 2.5D and 2D projectors, recess penetration gages, and ring gages to verify critical measurement points such as head diameter, head height, recess penetration depth, major diameter, thread angle, pitch, washer outside diameter, height, and recess diameter. Our production capabilities span head diameters from M1.6 to M16/#00 to 5/8" and lengths from 1/8" to 12" (3.175mm to 600mm), enabling customized solutions for OEM manufacturers requiring reliable, salt spray tested industrial fasteners for specialized applications.
