{"product_id":"m8-x-75-cup-square-bolt-din-603-a4-stainless-steel","title":"M8 X 75 Cup Square Bolt DIN 603 A4 Stainless Steel","description":"\u003cp\u003eThis M8 x 75mm coach bolt (cup square head bolt) is manufactured to DIN 603 in A4 stainless steel (316 grade). DIN 603 specifies a domed round head with a small square neck directly below the head. 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. When drawn into timber, the square neck embeds into the timber face and locks the bolt against rotation, so only the nut needs a spanner during tightening. The smooth domed head on the visible face reduces snag risk and gives a neat appearance.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTimber-to-timber and timber-to-steel connections with a flush round head\u003c\/li\u003e\n\u003cli\u003eGarden gates, fencing panels, and agricultural timber structures\u003c\/li\u003e\n\u003cli\u003ePlay equipment, outdoor furniture, and landscape installations\u003c\/li\u003e\n\u003cli\u003ePergolas, decking subframes, and structural outdoor joinery\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":57505089094007,"sku":"603A408075-D","price":13.09,"currency_code":"GBP","in_stock":true},{"title":"Pack of 50","offer_id":57505089126775,"sku":"603A408075-T","price":51.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/4728\/4855\/files\/simfix-20308050_1.png?v=1789550392","url":"https:\/\/simfix.com\/products\/m8-x-75-cup-square-bolt-din-603-a4-stainless-steel","provider":"Simfix","version":"1.0","type":"link"}
