{"product_id":"unc-unf-plain-hex-nut","title":"UNC UNF PLAIN HEX NUT","description":"\u003cp\u003eA Plain Hex Nut is a standard six-sided fastener with a \"plain\" (uncoated) finish, often referred to in the industry as a \"black\" finish. These nuts are identified by their thread type: UNC (Unified National Coarse) or UNF (Unified National Fine).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Differences: UNC vs. UNF\u003c\/strong\u003e\u003cbr\u003eThe primary difference is the Threads Per Inch (TPI). UNC has fewer, larger threads, while UNF has more, finer threads for the same diameter. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUNC (Coarse Thread):\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e General construction, wood, soft metals (like aluminium), and applications requiring fast assembly.\u003cbr\u003e\u003cstrong\u003ePros: \u003c\/strong\u003eLess likely to cross-thread, more tolerant of dirt or damage, and easier to install.\u003cbr\u003e\u003cstrong\u003eCons:\u003c\/strong\u003e Lower resistance to loosening from vibration compared to fine threads.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eUNF (Fine Thread):\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Automotive, aerospace, and precision machinery where space is limited or vibration is high.\u003cbr\u003e\u003cstrong\u003ePros:\u003c\/strong\u003e Higher tensile strength, better vibration resistance, and allows for finer tension adjustments.\u003cbr\u003e\u003cstrong\u003eCons:\u003c\/strong\u003e More susceptible to damage from cross-threading or over-tightening; requires cleaner threads for assembly. \u003c\/p\u003e","brand":"Bremick","offers":[{"title":"3\/8\" UNF","offer_id":47278385365186,"sku":null,"price":0.3,"currency_code":"AUD","in_stock":true},{"title":"7\/16\" UNF","offer_id":47278385397954,"sku":null,"price":0.5,"currency_code":"AUD","in_stock":true},{"title":"1\/2\" UNF","offer_id":47278385430722,"sku":null,"price":0.7,"currency_code":"AUD","in_stock":true},{"title":"5\/8UNC","offer_id":47278385463490,"sku":null,"price":1.0,"currency_code":"AUD","in_stock":true},{"title":"5\/8\" UNF","offer_id":47278385496258,"sku":null,"price":1.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/6335\/8914\/files\/PLAIN_HEX_NUT.jpg?v=1773890279","url":"https:\/\/www.srbindustrialsupplies.com\/products\/unc-unf-plain-hex-nut","provider":"SRB INDUSTRIAL SUPPLIES","version":"1.0","type":"link"}
