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 →M3 Brass Male–Female Hex Standoffs (5-Pack) | 6 mm Hex from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
Keep your PCBs neat, safe, and stackable with these M3 brass male–female hex standoffs. The 6 mm hex body gives a firm grip for tightening, while precision M3×0.5 threads ensure smooth assembly. Ideal for Arduino, Raspberry Pi HATs, sensor breakouts, and compact enclosures.
| Thread | M3 × 0.5 |
| Type | Male–Female hex standoff |
| Hex width (AF) | 6 mm |
| Material | Brass (natural finish) |
| Lengths | Varies by variant (select above) |
| Pack size | 5 pcs |
| Included screws | M3 machine screws (length matched to standoff) |
Yes. Most dev boards and HATs use M3 or 2.5–3.0 mm mounting holes; these M3 standoffs fit standard Arduino and many Pi accessories.
Male end: M3 × 0.5 stud. Female end: M3 × 0.5 internal thread.
Yes—matching M3 screws are included (quantity/length matched to the selected variant).
Note: Minor cosmetic marks may occur from bulk handling; this doesn’t affect performance.
