Bought these to replace the bolts that were included with a Ford Performance differential cover (made by Spicer) for my 2014 Ford Raptor. The included bolts seem to be grade 8 flange bolts with a serrated face. They did not hold well with one falling out, a few others coming loose. They are too short IMO so these fits the bill. The included washers are wide and spread the clamping force out. They torqued perfectly and I am sure will last forever. I'd 12pt-all-the-things of they weren't expensive ;-)
