ARP's Front Cover, Water Pump, & Alternator Bolt Kits - ARP's timing cover bolts are available in both polished stainless steel or black oxide finished chrome-moly. You can also choose between standard hex head or compact 12 point fasteners. These fasteners are also a part of ARP's complete engine bolt kits. Studs are preffered by many pro engine builders because they eliminate the chance of pinching the gaskets and contribute to easier engine assembly. You will note that ARp studs have a special "bullet" nose to guide the nut accurately into place. Studs are available in standard black oxide finish or polished stainless stell with hex or 12 point nuts. Alternators that come loose are a pain, so that's why ARP came up with these super tough bolts in your choice of black oxide finish or polished stainless steel. Both fasteners are rated at 170,000 psi.
