For about $63.75+shipping (IT'S ON SALE NOW) you can purchase a set (250 pieces) of sized Ground GAGE Pins.

My set is .251 to .500, 250 pins, .0002 minus (undersized). I use to measure the cylinder bores. The size of the pins are marked on them.

The set comes in a plastic carrying case 17x12x3 inches. A NICE set.

Pin set is from GRIZZLEY.Com
