Accurately measure bearing clearances.
Made from a special extruded plastic thread with accurately controlled crush properties; Plastigauge provides a fast and accurate way to check bearing clearances. Plastigauge is packaged in a calibrated envelope that not only protects the plastic threads; but also serves as a scale to measure the bearing clearance. One package contains enough Plastigauge to check both main and connecting rod clearance for one engine.
