0.032 a The taper per foot and diameter A at gage line are basic dimensions. Dimensions in Column A ′ are calculated for reference only. b Tolerances for diameter A are plus for plug gages and minus for ring gages. All dimensions are in inches. The amount of taper deviation for Class X, Class Y, and Class Z gages are the same, respectively, as the amounts shown for tolerances on diameter A . Taper deviation is the permissible allowance from true taper at any point of diameter in the length of the gage. On taper plug gages, this deviation may be applied only in the direction that decreases the rate of taper. On taper ring gages, this devi ation may be applied only in the direction that increases the rate of taper. Tolerances on two-deci mal dimensions are ± 0.010. British Standard Tapers.— British Standard 1660: 1972, “Machine Tapers, Reduction Sleeves, and Extension Sockets,” contains dimensions for self-holding and self-releasing tapers, reduction sleeves, extension sockets, and turret sockets for tools having Morse and metric 5 percent taper shanks. Adapters for use with 7 ⁄ 24 tapers and dimensions for spindle noses and tool shanks with self-release tapers and cotter slots are included in this Standard.
