It combines hex socket button head and cap head screws along with matching nuts, flat washers, and spring lock washers, providing a complete fastening solution for repair, assembly, and maintenance tasks.
- 【Grade 12.9 & 10.9 High-Strength Alloy Steel】Machine screws are manufactured from premium Grade 12.9 and 10.9 alloy steel, offering high tensile strength along with excellent resistance to wear and deformation. M3 Bolts are specifically designed for demanding applications requiring enduring fastening strength and structural stability.
- 【Black Zinc Plated Corrosion Resistance Finish】Each screw and fastener is coated with a black zinc plating layer to help resist rust and surface corrosion in everyday environments. The uniform black finish also delivers a clean, professional appearance suitable for electronic devices, machinery, and mechanical assemblies.
- 【Precision Metric Thread & Stable Hex Socket Drive】Accurate M3 metric threading ensures smooth engagement with nuts and tapped holes, reducing installation resistance. The hex socket drive design provides stable torque transfer during tightening, helping reduce stripping and improving fastening reliability in repeated use scenarios.
