DIN 6921 specifies a hex head screw with an integral flange beneath the head, spreading the clamping load without a separate washer. Property class A4-70 indicates a minimum tensile strength of 700 MPa - stronger than standard A4-50 and suited to structural fixings where higher clamping force is needed. The integral flange spreads clamping force over a wider bearing area than the head alone, protecting the surface and removing the need for a separate washer during assembly.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAssembly work where a separate washer slows fitting\u003c\/li\u003e\n\u003cli\u003eFixings into softer sheet, plastics, or castings\u003c\/li\u003e\n\u003cli\u003eVehicle, trailer, and machinery assemblies\u003c\/li\u003e\n\u003cli\u003eGuards, brackets, and general fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 10 to 50, with free next working day delivery on UK orders over £50 and 30-day returns.\u003c\/p\u003e","brand":"Simfix","offers":[{"title":"Pack of 10","offer_id":57505312506231,"sku":"6921A408025-D","price":5.44,"currency_code":"GBP","in_stock":false},{"title":"Pack of 50","offer_id":57505312538999,"sku":"6921A408025-T","price":16.96,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/4728\/4855\/files\/simfix-2210830_1.png?v=1789550450","url":"https:\/\/simfix.com\/products\/m8-x-25-hex-non-serrated-flange-screw-din-6921-a4-stainless-steel","provider":"Simfix","version":"1.0","type":"link"}
