This type of sunk key has a uniform height throughout the key at both ends. So it is named parallel keys. Tapered keys. Like parallel keys, this sunk key type doesn't have a uniform height, instead, they are tapered at the upper surface in the ratio of 1:100. So they are called tapered keys.

Taper 1:100 in a sunk key means that the key tapers by 1/100th of an inch for every inch of length. For example, if the key is four inches long, it will taper by 0.04 inches. This taper allows the key to fit securely in the mortise, providing a strong and secure connection between the shaft and the hub.

1. Rectangular sunk key. A rectangular sunk key is shown in Fig. 1. The usual proportions of this key are : Width of key, w = d / 4 ; and thickness of key, t = 2w / 3 = d / 6 where d = Diameter of the shaft or diameter of the hole in the hub. The key has taper 1 in 100 on the top side only. Fig. 1 Rectangular sunk key. [sam_block id="2โณ]

The taper on key or tapered key means the thickness of key reduces along its length. Both square an rectangular sunk keys are placed half in the shaft and half in the mating part or hub. The sunk keys are of the following types: (i) PARALLEL SUNK KEY: Parallel Sunk Key is uniform in width and thickness throughout.

Parallel sunk key: If no taper is provided on the rectangular or square sunk key, it is called parallel sunk key i.e. it is uniform in width and thickness throughout. It is used where the pulley, gear or other mating piece is required to slide along the shaft.
