These percentages exist in 303, 304 and 305 series stainless steels so 18-8 is used at times to designate any and all of those alloy groups.  18-8 stainless steel offers good corrosion resistance and machines easily but will over time stain in coastal environments.  They are also acceptable for use in ACQ pressure-treated lumber.\u003c\/p\u003e","brand":"FMW Fasteners","offers":[{"title":"Default Title","offer_id":53365300461881,"sku":"1303035","price":2.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/6067\/0009\/files\/media_bdc71b97-6009-44e2-aab1-88b2c9eec01e.jpg?v=1780803046","url":"https:\/\/makeitstudios.com\/products\/5-16-18-x-4-1-2-carriage-bolt-18-8-a2-stainless-steel","provider":"MakeIt Studio","version":"1.0","type":"link"}
