50Pcs Pure Copper Countersunk Screw Washers | CNC Accurate Flat Head Gaskets for Industrial/Automotive/Machinery | M3 - M6 Sizes, 90° Angle, Protection - Degradation (M5)
- Top-Grade Pure Copper Construction - These CNC-machined screw washers withstand degradation, humidity, and oxidation for extended performance in harsh environments. Ideal for industrial equipment and outdoor applications.
- Accurate Engineering - Countersunk washers feature exact 90° angles and standardized concentricity (M3-M6 sizes) for optimal bolt alignment. Smoothed edges minimize material damage during installation.
- Enhanced Load Distribution - Copper gaskets create 30% larger bearing surfaces than standard washers, reducing bolt loosening by 60% in high-vibration machinery and automotive systems.
- Universal Compatibility - Lightweight design (0.52g-2.35g per unit) works with wood, metal, and composite materials. Includes 50 washers for multiple repair scenarios.
- Industry Certified - All washers meet industrial fastener standards with exact thickness specifications (2.05mm-3.5mm). Non-conductive copper reduces electrical hazards in sensitive equipment.
