Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Secure your components and assemblies with these M3 Non-Slip Hexagon Nuts, designed to provide reliable fastening and help reduce loosening caused by vibration or movement. The hexagonal shape allows easy tightening and removal using a standard wrench or socket.
These compact metric nuts are suitable for use with M3 screws, bolts, threaded rods, and other compatible M3 fasteners, making them useful for electronics projects, robotics, 3D printer assemblies, DIY projects, mechanical equipment, and general repairs.
M3 Metric Thread – Compatible with standard M3 screws and bolts.
Non-Slip Design – Helps improve fastening stability and reduce unwanted loosening.
