Ideal for maintenance, restoration work, automotive applications, and general engineering.\u003c\/p\u003e\n\u003cp\u003eThe BSF thread form, introduced in 1908 and specified in BS84:1956, is based on the British Standard Whitworth profile but features a finer pitch (more threads per inch). This provides a greater tensile stress area and improved resistance to stripping compared to coarse thread forms. Fine threads also offer better performance where wall thickness is limited or where short engagement length is required.\u003c\/p\u003e\n\u003cp\u003eKey Features \u0026amp; Benefits\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompact die nut design for threading in confined or difficult-to-reach areas\u003c\/li\u003e\n\u003cli\u003eIdeal for chasing, restoring, or forming BSF external threads\u003c\/li\u003e\n\u003cli\u003eManufactured from durable chrome alloy steel\u003c\/li\u003e\n\u003cli\u003eSuitable for non-ferrous metals and plastics\u003c\/li\u003e\n\u003cli\u003eFiner BSF pitch increases tensile strength and thread engagement reliability\u003c\/li\u003e\n\u003cli\u003eNot suitable for high-precision or certified thread applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTechnical Specifications\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 5\/16\"\u003c\/li\u003e\n\u003cli\u003ePitch: 22 TPI\u003c\/li\u003e\n\u003cli\u003eThread Form: BSF (British Standard Fine)\u003c\/li\u003e\n\u003cli\u003eThread Angle: 55° Whitworth profile\u003c\/li\u003e\n\u003cli\u003eStandard: BS84:1956\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBSF die nuts are widely used in automotive restoration, vintage machinery repair, metal fabrication, and precision mechanical applications where fine-pitch British threads are required.\u003c\/p\u003e","brand":"BORDO INTERNATIONAL PTY LTD","offers":[{"title":"Default Title","offer_id":51458044526879,"sku":"4840-5\/16","price":30.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/2484\/1799\/files\/bordo-international-pty-ltd-dies-bordo-5-16-x-22-bsf-chrome-alloy-die-nut-9326518047001-1210685149.png?v=1765360201","url":"https:\/\/twineagleimports.com.au\/products\/bordo-5-16-x-22-bsf-chrome-alloy-die-nut","provider":"Twin Eagle Imports ","version":"1.0","type":"link"}
