Valve
Part #D20114
This safety valve is a genuine replacement part manufactured for use with air compressors. If the compressor's pressure switch malfunctions, and does not turn the motor off when the amount of pressure is met, the safety valve will open to release the extra air pressure. The amount of pressure required to open the safety valve is set by tension of the spring inside the valve. The spring can wear out, and leave the valve open at a lower pressure than what is set to turn the switch off, and will not allow pressure to build inside the tank. This safety valve has a thread sealant pre-applied, so additional thread sealant is not required, the safety valve is sold individually.

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.

Can't find this special screw used on many housings etc

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.
