Disk keys are usual­ly used, as with par­al­lel keys for ta­per con­nec­tions, to fix the po­si­ti­on of shaft and hub. This form-lo­cking con­nec­tion is used to trans­mit tor­que, for ex­amp­le, from the dri­ve shaft to the ge­ar wheel. Disk keys are al­so re­fer­red to as Woo­d­ruff keys.

The disk key is load-bea­ring by vir­tue of its la­te­ral­ly tight fit. It the­re­fo­re acts as a dri­ver and trans­mits the tor­que of the shaft to the com­po­nent to be dri­ven (dri­ve shaft) or the tor­que of the dri­ving com­po­nent to the shaft to be dri­ven (out­put shaft). The wheel on the ge­ne­ral­ly ta­pe­red shaft is se­cu­red axi­al­ly against dis­pla­ce­ment by a lock nut.

The stan­dards for disk keys by pat­tern and di­men­si­ons are set by DIN 6888. For the to­le­ran­ce of the slot width, a fit with P9 for a tight se­at or N9 for a light se­at are usual­ly used in ac­cordance with DIN 7155. The width of the disk key is the­re­fo­re equi­va­lent to a to­le­ran­ce h9 (lower de­via­ti­on = 0). The height of the disk is to­le­ra­ted to h12. De­sign and cal­cu­la­ti­on gui­de­li­nes for ma­chi­ne key con­nec­tions are set out in DIN 6892.
