A coupling portion has one end coupleable to a distal end of a measurement spindle. The measurement spindle is disposed on a gauge inspector and movable in a measurement axis direction. A cylindrical stem is insertable into a gauge holding member to hold the inserted stem. The stem slidably holds a spindle having a distal end on which a contact point of a gauge is disposed. A frame has a first end coupled to a second end of the coupling portion and has a second end to which the gauge holding member is mountable. The gauge holding member is held to the frame such that an axis of the stem runs along the measurement axis direction. As a result, inspection is performed easily and accurately in a reverse posture with a contact point facing upward when a gauge is inspected.

An article includes a molded plastic body that is comprised of a main body portion and a locator pin that projects from the main body portion. The locator pin includes a base at the main body and a pin that extends from the base and has a tip end. The base and the pin are of different sizes so as to form a ledge that faces away from the main body portion. The pin includes a parallel-sided portion that is located within a zone that starts at the base and terminates short of the tip end.

A wheel flange height difference detection and annular groove burr clearing device includes a turntable, a detection platform, a first intelligent compression meter, a second intelligent compression meter, a first burr cutter, a second burr cutter and the like.

A measuring device having a flange extending from a rule portion at one end and an ergonomic module on the other end. The ergonomic module has side surfaces which angle at the same angle as side edges of the flange to permit the measuring device to be supported on the side surfaces during use. A magnet may be encapsulated in the ergonomic module for supporting the measuring device when not in use. A thumb depression is formed in the ergonomic module to facilitate use by the user.

The Rivet Pattern Pitch Gauge is a tool designed to properly space rivets or other fasteners in an aircraft skin repair. The tool consists of a straight edge with measure markings, a row of teeth set at a forty-five degree angle, and a corner that has a half inch radius gauge built in. The tool uses the teeth, which are six times the diameter of the fastener in height and length, to evenly space the fasteners when laying out the aircraft skin repair. It is this spacing coupled with the forty-five degree angled teeth that allow for accurate and quick repair layouts and that differentiate the Rivet Pattern Pitch Gauge from other fastener spacing tools.

Disclosed is a system and method for using a digital measuring device to install a structure. For example, the system can be used to install hurricane shutters over a window or door of a dwelling. Alternatively, the system can be used to install decorative shutters, shelving, or window treatments. Other example will be readily apparent to those skilled in the art. The present system is beneficial in any situation where taking accurate measurements is critical to the proper installation of a structure. The system employs a digital measuring device that wirelessly communicates with a mobile computing device. In one embodiment, the measuring device is a tape measure and the mobile computing device is a phone or table computer. The mobile computing device is preferably used to demonstrate to the user what measurements need to be taken. After the user takes the required measurements, the accuracy and sufficiency of the measurements are thereafter confirmed via the mobile computing device.

Methods, devices, and kits for measuring and establishing a gap between two surfaces are disclosed, which include and involve the use of a plurality of gap-establishing elements. Each gap-establishing element consists of a three-dimensional object having a defined and consistent thickness across an area that spans at least a partial length of the three-dimensional object. In addition, each gap-establishing element is labeled with a number that is correlated with the defined and consistent thickness that applies to such gap-establishing element. The plurality of gap-establishing elements are configured to be stacked upon or combined with each other. Such gap-establishing elements are useful for measuring and establishing gap dimensions that are included within various structures and/or machines (including simple and complex machines).

An adjustable measuring tool includes an elongated tool body and an extensible portion slidably positionable within the tool body and extensible through an open end. A thin tab extends downwardly from a front body face and has flat front and rear surfaces for alignment with edges of materials to be measured or marked. In embodiments, a backset gauge extends forwardly from the tool body, for measuring or marking backsets such as for grout or mortar. The extensible portion, tool body, or backset gauge may include measuring indicia. Another embodiment includes an adjustable angle attachment having two arms continuously rotatable about a central pivot point, for precisely measuring angles or squaring the tool to an angled surface.

A device for finding the runout of a machine spindle. The device includes a ball bearing mounted to the end of a short, precision shaft. The ball bearing includes a pattern of dots or similar markings on an upper face of an outer ring of the bearing. The device is mounted into a chuck attached to a spindle and is lowered to the level of an edge of a workpiece. A workpiece edge is moved toward the bearing of the device. A machinist zero's out a digital position readout of the machine's lead screw dial when the workpiece first contacts the bearing. The machinist determines the amount of runout of the spindle by observing the motion of the pattern on the bearing as the workpiece moves from first contact with the bearing to a point when the bearing stops moving.

A measurement method includes a step of measuring an object to be measured and a reference object by a first measurement unit and a second measurement unit. The first measurement unit has a first displacement meter and a second displacement meter that face each other in a first direction and measure the distance from the object to be measured. The second measurement unit has a third displacement meter and a fourth displacement meter that face each other in the first direction and measure the distance from the reference object. A frame-like supporting member includes a first frame portion supporting the first displacement meter and the third displacement meter, a second frame portion supporting the second displacement meter and the fourth displacement meter, and a third frame portion and a fourth frame portion that connect both end portions of the first frame portion and the second frame portion to each other.
