The flat-cone head profile eliminates protrusions, making it well suited to applications where a clean, unobstructed finish is required.\u003c\/p\u003e\u003cp\u003eManufactured from A2 stainless steel (equivalent to AISI 304), the bolt contains approximately 18% chromium and 8% nickel, giving it good corrosion resistance across a wide range of indoor and outdoor environments. It performs reliably in wet and atmospheric conditions, though it is not recommended for marine immersion or highly chlorinated environments, where A4 (316) grade is the preferred choice.\u003c\/p\u003e\u003cp\u003eThe drive type is typically a hex socket (Allen key), and the bolt is commonly graded A2-70, indicating a tensile strength of approximately 700 MPa. It is manufactured to ISO 10642 and DIN 7991 standards, with mechanical properties defined under ISO 3506. Each bolt weighs approximately 25g.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConstruction — architectural metalwork, handrails, balustrades, cladding systems\u003c\/li\u003e\n\u003cli\u003eManufacturing — machinery assembly, equipment panels, fabricated assemblies\u003c\/li\u003e\n\u003cli\u003eFood and Beverage — stainless processing equipment, wash-down environments\u003c\/li\u003e\n\u003cli\u003eAutomotive and Transport — body panels, interior fittings, equipment housings\u003c\/li\u003e\n\u003cli\u003eMarine (Light Duty) — deck hardware above waterline, general fixings\u003c\/li\u003e\n\u003cli\u003eElectrical and HVAC — control panels, enclosures, ductwork systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSummary:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: M12 x 25mm\u003c\/li\u003e\n\u003cli\u003eMaterial: A2 Stainless Steel (AISI 304)\u003c\/li\u003e\n\u003cli\u003eHead Type: Countersunk, flush fitting\u003c\/li\u003e\n\u003cli\u003eDrive Type: Hex socket (Allen key)\u003c\/li\u003e\n\u003cli\u003eGrade: A2-70 (tensile strength approx. 700 MPa)\u003c\/li\u003e\n\u003cli\u003eStandards: ISO 10642, DIN 7991, ISO 3506\u003c\/li\u003e\n\u003cli\u003eWeight: Approx. 25g per bolt\u003c\/li\u003e\n\u003cli\u003eSuitable for indoor and outdoor use; not recommended for marine immersion or high chlorine environments\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Flocon","offers":[{"title":"M12 x 25mm","offer_id":58663179780480,"sku":"147.CSK.M12.025","price":0.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0524\/4531\/5228\/files\/Stainless_20Steel_20Countersunk_20Bolt_20A2.jpg?v=1786156461","url":"https:\/\/www.flocon.co.uk\/products\/stainless-steel-countersunk-bolt-a2","provider":"Flocon Valves Pipes \u0026 Fittings","version":"1.0","type":"link"}
