Working on electronics or PCB projects? These uxcell spring-loaded test probe pins are super handy. They have a spherical tip design that makes them easy to mount and use for testing connections. Each pin is about 33mm (1.3 inches) long overall, with a tip diameter of roughly 1mm (0.04 inches). The barrel size is about 25mm x 1.3mm. They come in a mix of gold-tone and silver-tone finishes, and you get a pack of 100 pieces (with a slight tolerance of +/-2%). The spring mechanism ensures good contact and compensates for small variations in height. They're widely used in data communication equipment, receptacles, PC boards, wire wrapping, and all sorts of prototyping or repair work. Whether you're building test fixtures, debugging circuits, or just need reliable probe points, these pins are affordable and effective. The net weight of the pack is around 24 grams. Keep a stash in your toolbox—you'll find uses for them all the time.
