§ 29. Mr. Mitchison
asked the President of the Board of Trade how many standard types of screw thread are in manufacture and in common use in this country; how many of those types are in common use abroad; and what steps are being taken to adopt uniform international standards of screw threads in the interests of our export trade.
§ Mr. H. Strauss
Three, Sir, including a unified thread introduced recently by agreement between the United States, Canada and this country, are in common use here. Two of these are in use abroad. The British Standards Institution, with the full co-operation of industry, is actively 183 engaged in international discussions designed to secure wider agreement on an international standard.
