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 →The M3 Stainless Steel Phillips Pan Head Screw with Captive Washer is a high-quality fastener designed for secure and reliable assembly in electronic, mechanical, industrial, and DIY applications. Made from durable stainless steel, it offers excellent resistance to rust, corrosion, and wear, making it suitable for both indoor and outdoor use.
Featuring a Phillips (cross) pan head and a pre-assembled captive washer, this screw provides better load distribution, helps protect mounting surfaces from scratches or deformation, and reduces the chance of loosening caused by vibration. The captive washer remains attached to the screw, making installation faster and preventing lost washers during assembly.
Available in multiple lengths, these M3 screws are ideal for use with threaded holes or matching M3 nuts in a wide range of equipment and projects.
