These nuts have serrations on the integrated washer giving it a “locking” characteristic. 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. -All Nuts are Coarse SizeDrive SizeFlange DiameterFlange Nuts Serrated1/4”-207/16”0.625”5/16”-181/2”0.672”3/8”-169/16”0.75”1/2”-137/8”1.031”
