BRIEF HISTORY
The IS0 Recommendation R 885, Bolts and screws - Radii under the head for general purpose
bolts and screws - Metric series, was drawn up by Technical Committee ISO/TC 2, Bolts, nuts and
accessories, the Secretariat of which is held by the Deutscher Normenausschuss (DNA).
Work on this question by the Technical Committee began in 1959 and led, in 1965, to the
adoption of a Draft IS0 Recommendation concerning radii under the head of general purpose bolts
and screws up to 39 mm thread diameter for the metric series and up to 2 in for the inch series.
This first Draft IS0 Recommendation (No. 987) was circulated in May 1966 to all the IS0
Member Bodies for enquiry and was approved by a majority of IS0 Member Bodies. However, at a
meeting held in October 1966, the Technical Committee recommended the establishment of a second
Draft IS8 Recommendation relating to bolts and screws with thread diameters up to and including
150 mm, and proposed a separate Draft IS0 Recommendation for inch series bolts and screws.
In August 1967, this second Draft IS0 Recommendation was circulated to ail the IS0 Member
Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by the
following Member Bodies :
