(BSW)<\/a>: <\/strong>Developed by Joseph 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\u6807\u51c6\u7ec6\u7259\u87ba\u7eb9 (BSF)<\/a>:<\/strong> BSF threads are a variant of BSW, also featuring a 55-degree thread angle but with a finer pitch than BSW. They are used in applications requiring higher strength and tighter fits.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong><a href=\"https:\/\/www.britishmetrics.com\/images\/pdf\/technical\/bspp_bspt_4.htm\">\u82f1\u56fd\u6807\u51c6\u7ba1\u87ba\u7eb9 (BSP)<\/a>: <\/strong>BSP threads are used for pipe connections and have a thread angle of 55 degrees. 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\u87ba\u7eb9\u534f\u4f1a (BA)<\/a>:<\/strong> BA threads have a thread angle of 47.5 degrees and are primarily used for small screws and bolts.
