ASSY VALVE PLATE
Part #Z-AC-0032
This replacement valve plate assembly is a high quality item designed for use on Craftsman air compressors. It is a genuine manufacturer sourced item that is used to control the airflow into the cylinder. Once the piston starts traveling up, the reeds on the valve plate open and air is sent into the air tank. Overtime the reeds will get worn eventually requiring valve plate replacement. One metal valve plate with reed valves and two rubber seals are included in this assembly. When replacing this valve plate assembly it is also a good time to replace the head gaskets which are sold separately. You will need a wrench set to complete this repair.

Actually don't like using Torx bits because they are hard to center deep in the channel. I had misplaced these forcing me to order replacements.
My plan is to insert Torx bits before screwing in and using jb weld to secure the bit to the screw, giving me a hex head. Can't find this special screw with a hex head. This screw is called AGC-408 by craftsman.
