Description
4-40 thread, 1/4" length, 1/4 hex
Great for general purpose standoff to keep your development board off the bench, but these 1/4" male/female hex standoffs are also the specified size for the Chameleon 1 enclosure. If you mount your board on this size standoff, it will be the right height to fit the faceplate on the Chameleon 1 (for supported boards).
Try finding this size at this price at your local Radio Shack or home improvement store - you can't!
