            High Quality

            Exactly what I needed to replace the rusted bolt and washer when I changed out my Harmonic Balancer

            Cheap insurance

            This item is not cheap for a bolt and washer, but it's far cheaper than completely tearing down your engine and replacing the crankshaft when your Harmonic Balancer works loose and ruins the nose because of an inferior fastener. I'm always confident with ARP quality.
