M8 Serrated Flange Hex Lock Nuts 316 Stainless Steel 5 Pcs

A 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.
