DIN 6331 specifies a hexagon nut with an integral flanged collar, for spreading the clamping load without a separate washer. The collar bears on a wider area than the flats alone, protecting the surface and reducing the chance of pull-through.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSheet metal and panel fixing\u003c\/li\u003e\n\u003cli\u003eAssemblies where a washer would be lost\u003c\/li\u003e\n\u003cli\u003eMachinery and equipment mounting\u003c\/li\u003e\n\u003cli\u003eGeneral engineering assembly\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.
