Abstract: A caliper has a main scale (1) having an inside-measuring jaw (2) and an outside-measuring jaw (3) and a slider (11) having an inside-measuring jaw (12) and an outside-measuring jaw (13) further includes a tube-shaped grip (30) provided on an end of the main scale (1) capable of movement in a longitudinal direction of the main scale (1), the grip (30) including a means for fixing the grip (30) relative to the main scale (1).

Abstract: An assembly and kit adapted to receive an indicator for indicating a dimension of an object corresponding to a distance between two contact points having a moveable indicator pin defining one of the contact points, having: an elongated generally rectangular gauge body having a longitudinally extending recess; an adjustable device for fine adjustment of the depth and longitudinal position of the indicator pin extending at least partially through the recess of the gauge body; an anchor pin for extending downwardly from a gauge body defining the other contact point; and extension structure for course adjustment of the distance between the contact points a predetermined fixed amount, the anchor pin means being couplable to the gauge body or the extension structure.

Abstract: Apparatus and an associated method for determining the deviation of the distance between two points on a first object and the distance between two points on a second object. The apparatus and associated method are useful when measuring dimensions of short turn bores and O-ring grooves.

Abstract: A gauge to evaluate the flatness, planar disposition, and location of the sealing surface of a rotary shouldered threaded connection, the gauge being adjustable and convertible to gauge either pin or box ends of different size connections, with multiple contact shoes engaging the connection threads to hold the gauge fixed relative to the thread pitch diameter and a device to measure distances from the pitch diameter to the shoulder face. In the method, the gauge is moved around the connection to obtain measurements from different circumferential locations to evaluate shoulder flatness and axial location and to examine the angular disposition of the plane of the shoulder face relative to the thread axis.
