Methods and devices for ring sizing are described, including a ring sizing device that may be affixed to a platform, that allows users to evaluate ring sizes. The ring sizing device may include a stationary panel and a movable panel, where the stationary panel may include a bottom portion configured to be affixed to a mounting platform and a top portion having a top edge with one or more semicircular-shaped notches. The movable panel may be coupled with the stationary panel and configured to move relative to the stationary panel. The bottom edge of the movable panel also may include one or more semicircular-shaped notches and the combination of the panels may form one or more ring sizing holes that have an associated first height when the movable panel is in the first position and a larger second height when the movable panel is in the second position.

A system and method for measuring an inside diameter of a pipe to determine if it exceeds a predetermined value using a plurality of fingers operatively connected to a spring. When in a fully extended position, the distance between opposite fingers is the predetermined value. The fingers are pivotable between a starting position, through the fully extended position, and to a failing position. In the starting position, an outer end of each finger engages an inside surface of the pipe to compress the spring. If the diameter exceeds the predetermined value as the system moves through the pipe, the pipe inside surface will no longer engage the fingers, which releases the spring causing the fingers to pivot to the failing position, where they remain until the system is removed from the pipe and manually reset.

The present disclosure relates to a pipe flange standard identification tool and a system. In one aspect, the valve identification tool includes a pair of spaced-apart apertures and bears information identifying a valve having a pair of adjacent flange bolts with a spacing therebetween, which matches the spacing between the apertures. Also disclosed is a set of the above-described valve measurement tools, and a kit having a plurality of the tool sets. In one form, each of the tools in a given set corresponds with a valve listed in a common standard.

A thread gauge, which allows to reliably know the time for replacement by visual checking and improves the predetermined dimensional accuracy of a thread product has a go-side thread measuring portion extending from one side of a shank portion coaxially with the shank portion or a not-go-side thread measuring portion extending from an other side of the shank portion coaxially with the shank portion, a wear checking gauge line having a predetermined length and a predetermined depth formed on male thread portions and female thread portions formed on the go-side thread measuring portion or the not-go-side thread measuring portion.

A flatness measuring apparatus includes a measuring assembly and a movable assembly. The measuring assembly includes a measuring unit. The measuring unit includes a supporting base, a loading block, and a limiting block mounted above the supporting base. The supporting base defines a receiving hole. The loading block is removably received in the receiving hole. The loading block is coplanar with the supporting base and cooperatively defines a limiting channel. A distance between the limiting block and the supporting base is substantially the same as a maximum allowable height of a workpiece, thereby only allowing qualified workpieces to slide therethrough and catching unqualified workpieces. The movable assembly connects to the measuring assembly to drive the loading block to disengage from the receiving hole and make the unqualified workpieces drop down from the measuring unit.

A nail gauge tool is provided for quickly and accurately measuring nail shape and nail size. The nail gauge offers several arch-shaped openings for matching to and measuring a natural nail. As the measurement result, the nail arch shape information and nail arc length information along the natural nail's width direction are obtained for manufacturing custom-fit artificial nails. The nail gauge tool is advantageously small and suitable for use inside a nail salon.

Ammunition measurement tools include a frame having a reference surface adapted to contact a first caliper jaw of a pair of calipers, a gauge element attached to the frame and movable, the gauge element defining a plurality of apertures of different selected diameters, each aperture diameter corresponding to a diameter of a selected part of a cartridge, the gauge element being operable to move to position a selected aperture in registration with a second jaw of the pair of calipers such that the distance from the aperture to the second jaw may be measured to determine a length dimension of a cartridge positioned in the aperture. The gauge element may be rotatably connected to the frame to rotate about an axis. The frame may include an attachment facility operable to secure to the jaw of a pair of calipers.
