{"product_id":"m12-square-nut-din-557-a2-stainless-steel","title":"M12 Square Nut DIN 557 A2 Stainless Steel","description":"\u003cp\u003eThis M12 square nut is manufactured to DIN 557 in A2 stainless steel (304 grade). DIN 557 specifies four flats instead of six, for holding in a slot or channel where a hexagon would turn. The flat sides sit against a channel wall or timber, so the nut is held from turning while the bolt is tightened from one side.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eChannel and strut fixing\u003c\/li\u003e\n\u003cli\u003eTimber and sheet metal work\u003c\/li\u003e\n\u003cli\u003eMachine guards and frameworks\u003c\/li\u003e\n\u003cli\u003eSign and panel mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 20 to 100, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
