Conical plunger centers itself on multiple diameters
The 0.875THSC magnetic adapter is used to gather quick data points over a range of hole sizes using a single adapter. The secret is a spring-loaded, cone-shaped, locating plunger (see illustration below). This adapter will locate on hole sizes 0.100" to 0.625" (2.5 mm to 15.9 mm). Keep in mind that we can also make these adapters to fit other hole diameters on request. Three strong magnets on the bottom keep the adapter squarely on any ferrous surface, and counteract the spring-loaded force of the plunger. The adapter is reliable and repeatable. A knurled profile around the outer perimeter assists in removal after measuring is finished. The adapter holds the centerpoint of a 0.875" diameter SMR 1.500" (or 40 mm for the metric version) above the surface of the part and on centerline of the hole to a tolerance of ±0.0005" (±0.013 mm). The SMR seats on a conical land and is held in place by a magnet.
