Massive Speed Precision Fasteners Zetec Cam Cap Hardware Kit MAHW'8592ZETEC CAM CAP HARDWARE KIT - Kit consists of 20 New Hex Head Cap Screws, 20 extra thickness case hardened washers, and a 2 Oz. container of Royal Purple Max-Tuff Assembly Lube to complete the job. The benefits are several here. Not only are you doing away with those odd reverse torx head bolts Ford gives us that you can never find the right socket for, but your going to a superior strength fastener. The traditional hex head means you'll always have the right socket on hand as well. We're also utilizing a separate washer from the bolt itself, greatly reducing the twisting forces imposed in the original design. Don't do cams without it.
