These ARP fasteners give the oil pan a clean, purposeful performance-engine look while putting quality hardware where it belongs. The conventional hex head is familiar to anyone who has spent time wrenching on small-block Chevy and LS engines, making this a straightforward choice for an engine build, restoration or performance project.
