{"product_id":"m20-hex-castle-nut-din-935-a4-stainless-steel","title":"M20 Hex Castle Nut DIN 935 A4 Stainless Steel","description":"\u003cp\u003eThis M20 castle nut is manufactured to DIN 935 in A4 stainless steel (316 grade). DIN 935 specifies a hexagon nut with slots cut across the top face, for locking with a split pin through a drilled bolt. 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. A split pin passes through the drilled bolt shank and into one of the slots, giving a positive mechanical lock that cannot vibrate loose and can be checked at a glance.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWheel bearings, hubs, and axle assemblies\u003c\/li\u003e\n\u003cli\u003eAgricultural and plant machinery linkages\u003c\/li\u003e\n\u003cli\u003ePivot pins and clevis joints\u003c\/li\u003e\n\u003cli\u003eSafety-critical joints requiring a positive lock\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 5 to 25, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.\u003c\/p\u003e","brand":"Simfix","offers":[{"title":"Pack of 5","offer_id":57506144354679,"sku":"935A420-D","price":16.17,"currency_code":"GBP","in_stock":true},{"title":"Pack of 25","offer_id":57506144387447,"sku":"935A420-T","price":73.24,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/4728\/4855\/files\/simfix-23508_1.png?v=1789550503","url":"https:\/\/simfix.com\/products\/m20-hex-castle-nut-din-935-a4-stainless-steel","provider":"Simfix","version":"1.0","type":"link"}
