ARP BB Chevy SS Hex Oil Pan Bolt Kit 

Hex Bolt Kit, Stainless 300, Big Block Chevy

The engineers at ARP spent quite a bit of time developing these highly effective, unique oil pan studs. They're designed to make it as easy as possible to install a pan and seal it properly. You'll note that the studs have a radiused bullet nose that serves to locate the pan rails, then allow the nuts to be easily installed without the worry of cross-threading. For those who prefer bolts, ARP's got you covered, too. Both are available in black oxide finished chrome moly steel or rust-proof stainless steel. Also, take your pick from conventional hex nuts (or bolt heads) and a space-saving 12-point design. The stud kits come complete with a special locking flanged nut, while the bolt kits come with washers.
