This set includes the shown bolts for mounting the oil pan onto the block in the factory configuration. This kit is intended to use the original studs and does not include those. These are finished in yellow zinc. These bolts are the correct 18mm length that is the same as the OEM bolts - not slightly longer or shorter like most replacement kits on the market.
