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).

A depth gauge is provided that is configured to be removably coupled to a tool. The depth gauge having a gauge body, a coupling means to removably couple the gauge body to the tool and a fiducial on the gauge body whereby the fiducial signifies a distance between the fiducial and a portion of the tool. In some embodiments, the coupling means comprises a magnet. In some embodiments, the tool is a wire stripper whereby when the wire stripper is actuated on a coated wire, the wire stripper cuts a portion of the wire coating equal to the distance defined by the fiducial. In some embodiments, the fiducial comprises an abutment protruding from the gauge body. In some embodiments, the depth gauge has multiple fiducials and the gauge body and the fiducials are formed as one piece.

Provided, in one aspect, is a groove measurement system. The groove measurement system, according to this aspect, includes a go measurement apparatus, the go measurement apparatus having first and second go gages protruding from one or more surfaces thereof, the first go gage having a go width (W.sub.G) generally equal to a minimum desirable groove width (W.sub.MI) of a desired groove, and the second go gage having a go depth (D.sub.G) generally equal to the minimum desirable groove depth (D.sub.MI). The groove measurement system, according to this aspect, additionally include a no-go measurement apparatus, the no-go measurement apparatus having first and second no-go gages protruding from one or more surfaces thereof, the first no-go gage having a no-go width (W.sub.NG) greater than the maximum desirable groove width (W.sub.MA), and the second no-go gage having a no-go depth (D.sub.NG) generally equal to the maximum desirable groove depth (D.sub.MA).

A multi-function gauge block has a rectangular body member with four side faces and two end faces that define outside measuring faces which define a precise length therebetween and which can be wrung to other gauge blocks or to a platen. An angle face extends between two of the side faces and forms a precise angle between itself and one or both of these side faces. The angle face is bounded by a pair of inside measuring faces that define a precise length therebetween. The multi-function gauge block has a precise mass so that it can be used as a calibration weight.

A device for checking gap tolerance between an adjustable portion of a brake switch and a brake pedal includes a handle and one or more probes extending from the handle. Each of the one or more probes include jaw portions defining multiple stepped regions of increasing thickness with decreasing distance from the handle and a slot extending through the multiple stepped regions. The slot is configured to be inserted between the adjustable portion of the brake switch and the brake pedal. A dimensional tolerance of the slot in at least one of the stepped regions equals a preset gap tolerance between the adjustable portion of the brake switch and the brake pedal.

The invention relates to an evaluation tool and method for inspecting the integrity of any physical industry connections (hereinafter fittings). The tool comprises a first component (21) provided with a recess (23) to facilitate its engagement with a fitting to be evaluated (see FIG. 10); and a second component (20) connected to, and moveable relative to, the first component (21). Movement of the second component (20) relative to the first component (21) establishes a measurement between two surfaces (32, 33 in FIG. 10) of a fitting (34) to be evaluated, e.g. between an adjustable ferrule or nut (32) and a fixed part (33) of a fitting (34). The measurement is directly (27, 28), or indirectly, indicative of one or more predetermined connection conditions (e.g. over or under tightening of the adjustable component). The predetermined connection conditions may be read directly from the tool, remotely via an electronic device, or by late cross-referencing against entries in a database.
