These hardened, parallel-ground ARP chrome moly washers are ideal for distributing a clamp load over a larger area than standard washers.
These 3/8" ID washers have an oversized 0.675" OD that is la little arger than the 0.625" OD of AN960-618 washers but much smaller than the 1 5/8" OD of AN970-6 washers. Extra-thick 0.120" thickness is almost like stacking 2 AN960-616 washers. Black oxide finish. Sold in packs of 10.
