This Standard is intended to cover the complete dimensional and general data for taper pins, dowel pins, straight pins, grooved pins, and spring pins recognized as American National Standard, which are widely used in general industrial applications. Also included are appendices providing supplementary information for the drilling of holes for taper pins and the testing of pins in double shear. The inclusion of dimensional data in this Standard is not intended to imply that all of the products described are stock production sizes. Consumers are requested to consult with manufacturers concerning availability of product.<\/p>\n
