MPN: PCE318.1005 UPC: 840136542360
PCE black-oxide coated chromoly 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.
