Taper pins shall have a uniform,taper over the pin length with both ends,crowned. Most sizes are supplied in both,commercial and precision classes, the latter,having generally tighter tolerances and being,more closely controlled in manufacture.,Dimensions for both classes are given in,Table 1,1.3 Dimensions.,All dimensions in this standard are given,in inches, unless otherwise stated.,1.4 Options.,Options, where specified, shall be at the,discretion of the manufacturer, unless otherwise,agreed upon by the manufacturer and,purchaser.,1.5 Terminology.,For definition of terms relating to fasteners,or component features thereof used in,this standard, refer to Glossary of Terms for,Mechanical Fasteners, ANSI/ASME B18.12,page M-1.,2.

The major diameter, A,of both commercial and precision classes of,pins, specified in Table 1, is the diameter at,the large end and is the basis for the pin size.,2.1.2 Diameter at Small End. The diameter at,the small end of pins, 8, is a function of the,length and should be specified as a reference,dimension for determining drilled hole size,see Appendix I.
