360pcs Stainless Steel Ring Washers Set 8 Sizes In A Storage Box

2 Set Accessories:1 Set stainless steel washers & Hex Flange NutA flange nut is a nut that has a wide flange at one end that acts as an integrated, non-spinning washer.This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.The flange may be serrated to provide a locking action. The serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut.Because of the serrations they cannot be used with a washer or on surfaces that cannot be scratched. The serrations help in avoiding vibration of nut and increase the holding power of nut.Material: Stainless SteelColor: Silvertainless steel washers:corrosion resistantWith a rugged convenient re-sealableUsed for sump plugs, automotive brake lines, fuel, oil lines, hydraulic accessories, waterAssortment washer Kits fit for most of engines, such as generators, marine, cars, machinery and factorysize: M2 * 5 * 0.5mm(ID x OD x Thickness)M2.5 * 5 * 0.5mm(ID x OD x Thickness)M3 * 7 * 0.5mm(ID x OD x Thickness)M4 * 9 * 0.8mm(ID x OD x Thickness)M5 * 10 * 1mm(ID x OD x Thickness)M6 * 12 * 1.5mm(ID x OD x Thickness)M8 * 16 * 1.5mm(ID x OD x Thickness)M10 * 20 * 2mm(ID x OD x Thickness)Hex Flange Nut:Thread Size: M6;Product Name: Hex Flange NutHeight: 5.6mmHex Size: 9.6mmThread Pitch: 1mm;Flange Diameter: 12.95mmPackage Content:360 * stainless steel washers25 Pcs * Hex Flange NutOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
