Talk:British Standard Whitworth

From Wikipedia, the free encyclopedia

The contributor of the original article is an American, so I'm going to assume his comments on BSW no longer being used apply particularly to the USA. It's certainly not true in Australia; Nearly all the bolts and machine screws available for sale in hardware stores here are still BSW. Andrewa 06:37, 9 August 2005 (UTC)

• As an American, the last time that I saw BSW bolts, screws, and hand tools in the US was in use on British autos and motorcycles dating to the mid 1960's -- or somewhat later.--TGC55 16:28, 4 March 2006 (UTC)

Amazing! Are there special cars, appliances , bicycles etc. made for Australia? Each of these industries converted to ISO standard (metric) screws long ago, even Detroit. How do you find bolts for stuff manufactured abroad? 82.181.150.151 19:59, 8 November 2006 (UTC)

• • • The article sees from a narrow US view. BSW, BSF, WF, WWF etc. are all Whitworth threads. They were the first thread standards and as Andrew A mentions are still in popular use throughout the world. ISO is a modern preferance but it is not universal. For example, every camera and tripod still uses Whitworth threading, even modern digital ones. Microscopes use standard interchangeable items with British Microscope Society thread which is a Whitworth format. I suspect telescopes and other optical items also follow the standard as they were early adopters of standard threading and likely therefore to be late chnagers to other more recent standards. It is in fact the US that is still pretty isolated with its own system of imperial non-global threads that are certainly not sold much elsewhere whereas we can get just about everything from Whitworth to ISO or even British Standard Pipe Thread :-) Paul J.
