These are a small tapered pin that fits tightly into a #66 drill hole. They come as a stick of perhaps 50 pins - you simply insert the leading edge of the first pin into the hole, push to lodge it into the hole, then bend sideways to break the pin from its neighbor on the stick. Fast and inexpensive. Sorry - I don't know where to purchase them now - we get ours from a local distributor. dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
