Having difficulty attaching a PCB? This kit is especially useful when there are no mounting holes - as with the original Raspberry Pi. Instead of gluing, taping, epoxying, etc. use these elegant standoffs. They have these round hook things that are designed to grip standard 0.062" thickness PCBs either by the edge or by the corner.Comes in a pack of 4 with matching #6 thread forming screws. Ideal for use with up to 1/8" mounting material. We have these as part of the Pi Dish kit and they work really well!
