gage, flat plug: a plug gage made in the form of a central axial segment of a plain cylindrical plug gage. gage, flush pin: a gage for checking the distance between two surfaces, comprising a body having a through hole, and a pin in the hole that projects from a face of the body a distance equal to the dimension to be gaged when the opposite or indicating end of the pin is flush with the opposite face of the body. The indicating end of the pin or the adjacent face of the body has a step of a depth equal to the tolerance of the dimension gaged. gage, involute spline: a gage having on its gaging circum- ference a number of involute shaped teeth that corre- spond in contour, number, diameter, and spacing with the product specification. gage, plain adjustable snap: a complete external caliper gage employed for the size control of plain external dimensions, comprising an open frame in both jaws of which gaging members are provided, one or more pairs of which can be set and locked to any predetermined size within the range of the gage. gage, plain cylindrical plug: a complete internal gage of a single- or double-ended type for the size control of holes and other applications. It consists of a handle and a gaging member or members, with suitable locking means. gage, plain ring: an external gage of circular form employed for the size control of external diameters. In the smaller sizes itmay consistofa gage body into which is pressed a bushing, the latter being accurately finished to size for gaging purposes. gage, plain solid snap: a complete external caliper gage employed for the size control of plain external dimen- sions, comprising an open frame and jaws, the latter carrying gaging members in the form of fixed, parallel, nonadjustable anvils. gage, progressive cylindrical plug: a complete internal gage consisting of a handle and a gaging member in which the GO and NOT GO gaging sections are combined in a single unit secured to one end of the handle. gage, serrated spline: a gage having on its gaging circum- ference a number of straight-sided triangular shaped teeth that correspond in angle contour, number, diame- ter, and spacing with the product specifications. gage, spline plug: a plug gage having a series of projecting keys, equally spaced about the periphery, that fit into the spline-ways to be gaged. gage, spline ring: a ring gage having keys that are comple- mentary to the splined shaft to be gaged. gage, straight-sided spline: a gage having on its gaging circumference anumberofkeysorkeyways withparallel sides that correspond in width, number, spacing, and diameter with the product specifications. 2 gage, taper lock plug: a plug gage in which the gaging member has a taper shank that is forced into a taper hole in the handle. This design is standard for plug gages in the range above 0.059 in. to and including 1.510 in. and for pipe-thread plug gages to and including 2 in. nominal pipe size. (The wire type plug gage is standard in the range above 0.010 in. to and including 1.010 in. See definition of wire type plug gage.) gage, taper plug: an internal gage in the form of a frustum of a cone having diameter, taper, and length suitable for the internal gaging of taper dimensions in accordance with the specifications of the product. An extended por- tion may be provided for checking a tang slot when specified. gage, taper ring: an external gage, the internal contour ofwhich conforms to the frustum ofa cone having diam- eter, taper, and length suitable for the gaging of external taper dimensions in accordance with the specifications of the product. An extended portion may be provided for checking a driving tang when specified. gage, threadplug: acomplete internalthreadgageofeither single- or double-ended type, comprising a handle and a threaded gaging member or members, with suitable locking means. gage, thread ring: an external thread gage employed for the size control of threaded work, with means of adjust- ment provided. gage, trilock plug: a plug gage in which three wedge- shaped locking prongs on the handle are engaged with corresponding locking grooves in the gaging member by means of a single through screw, thus providing a self-centering support with a positive lock. This design is standard for plug gages in the ranges above 0.760 in. to and including 8.010 in., with the exception of pipe thread plug gages, for which it is standard in the ranges above 2 in. nominal pipe size, to and including 6 in. nominal pipe size. gage, wire type plug: a plug gage comprising a gaging member of straight cylindrical section throughout its length held in a collet type handle. This design is stan- dard in the range above 0.010 in. to and including 1.010 in. gaging button: an adjustable gaging member ofan adjust- able snap or length gage, consisting of a shank and a flanged portion, the latter constituting the gaging section. gaging member: integral unit of a gage that is accurately finished to size and is employed for size control of the work. In taper lock plug gages, the gaging member con- sists of a shank and a gaging section. gaging section: portion of the gage that comes into physi- cal contact with the work. In the plug range above 1.510 in. to and including 12.010 in. the gaging section is identical with the gaging member.
