Product Description
ARP's rugged, black-oxide coated chromemoly intake manifold bolts are rated at 170,000 psi. They're precision-machined for optimum thread engagement and have a wide-area flange for better load distribution. They also feature precision-rolled threads, which prevent galling, while promoting more consistent torque loading. These bolts are available with either hex or 12-point heads, and washers are included.
