BRIEF HISTORY
The IS0 Recommendation R 773, Rectangular or square parallel keys and their corresponding keyways
(Dimensions in millimetres), was drawn up by Technical Committee iSO/TC 16, Keys and keyways, the
Secretariat of which is held by the Institut Belge de Normalisation (IBN).
Work on this question by the Technical Committee led in 1965 to the adoption of a Draft IS0 Recommen-
I dation.
In November 1966, this Draft IS0 Recommendation (No. 1084) was circulated to all the IS0 Member
Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by the following
Member Bodies :
Argentina Greece Spain
Austria Hungary Sweden
Belgium India Switzerland
Brazil Italy Turkey
Chile Japan U.A.R.
Denmark Korea, Rep. of United Kingdom
France Netherlands U.S.S.R.
Germany South Africa, Rep. of Yugoslavia
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which decided.
in January 1969, to accept it as an IS0 RECOMMENDATION.

I SO Recommendation R 773 January 1969
RECTANGULAR OR SQUARE PARALLEL KEYS
AND THEIR CORRESPONDING KEYWAYS
(Dimensions in millimetres)
1. SCOPE
This IS0 Recommendation specifies the dimensional characteristics of rectangular or square parallel keys and of
their corresponding keyways in shaft and hub. It also gives the relations which should be observed between the
diameter of shaft and section of key.
2. FIELD OF APPLICATION
This IS0 Recommendation is for general purposes, for cylindrical shaft ends*, but it is recommended that the
values given be adhered to even for special applications.
Attention is drawn to the fact that some IS0 Recommendations, published previously, give dimensions and
tolerances other than those appearing in the present 1SO Recommendation.
