Whitworth in 1841, BSW threads were the first standardized thread form and were once widely used in the UK and former British colonies. They have a 55-degree thread angle with rounded crests and roots. BSW threads are primarily used in general mechanical engineering and building structures, suitable for rougher machining environments.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong><a href=\"https:\/\/www.britishmetrics.com\/images\/pdf\/technical\/bsfstd_1.htm\">\u82f1\u56fd\u898f\u683c\u7d30\u76ee\u306d\u3058 (BSF)<\/a>:<\/strong> BSF threads are a variant of BSW, also featuring a 55-degree thread angle but with a finer pitch than BSW.

There are two main types: BSPP (parallel threads) and BSPT (tapered threads). BSPP threads are usually sealed using a sealing face or an O-ring and are commonly used in hydraulic and pneumatic systems. BSPT threads primarily rely on the thread itself for sealing; the interference fit between the threads forms the seal, making them suitable for high-pressure sealing in piping systems.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong><a href=\"https:\/\/www.britishmetrics.com\/images\/pdf\/technical\/ba(1).htm\">\u82f1\u56fd\u5354\u4f1a\u30b9\u30ec\u30c3\u30c9 (BA)<\/a>:<\/strong> BA threads have a thread angle of 47.5 degrees and are primarily used for small screws and bolts.
