Working Principle - Double action handles are rigidly attached to the contact plungers and are automatically self-centering.
Function - Assist in quick checking of holes, slots and recess up to 6 inch deep.
Scope of Application - Telescopic spring piston in the hole (or groove), can conduct inner diameter detection, used with micrometer or caliper, with knurled locking device.
Advantage - The ends of both contact are head treated steel and precision ground to a radius allowing proper clearance on the smallest hole the gauge will enter.
Super Quality - Self centering telescoping gauge has high rigidity, good wear resistance, durable in use.
