DRAIN VALVE
Part #N286039
When using an air compressor, moisture naturally builds up inside the tank as air is compressed. If this water isn’t drained regularly, it can lead to internal rust and damage over time. That’s where the drain valve comes in—it allows you to release the built-up water and keep your tank in good condition. Located at the bottom of the tank, this valve should be opened after each use to prevent corrosion and extend the life of your compressor. If you tend to leave air in the tank for long periods, water accumulation can be even more significant. This replacement drain valve features a thread size of 18 TPI and is sold individually. Regular maintenance with a working drain valve helps ensure safe and efficient compressor operation.

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.
