INTRODUCTION — The general practice in industry is to supply coupling hubs without fillet radii in the keyway corners to permit the use of standard commercial keys instead of keys with chamfered. (hole) • In the context of tolerances, these features need not (necessarily) be of cylindrical profile: • a key is an external feature • a keyway is an internal feature • a “hole or shaft can be taken as referring to the space contained by (or containing) the two parallel faces (or tangent planes) of any workpiece, such as the width. These shafts have keyways only on the ends, leaving a plain shaft in the center. 1 -1967 (2004) standards for metric and inch unit systems. 000 on the width and ends of the keyway, +0. 0010".
