DraftFit reference page for DIN 6885-1 parallel-key and keyway dimensions used in shaft connections.
Reference
DIN 6885-1:2021-11
DIN Media lists DIN 6885-1:2021-11 as the current edition.
What the standard provides
DIN 6885-1 standardizes dimensions, tolerances and related data for deep-pattern parallel keys and keyways across shaft-diameter ranges.
Selection vs strength
Selecting the standardized key cross-section is not the same as proving the connection. Torque, key length, hub material, shaft material and allowable contact pressure can govern the final design.
