I am trying to help my son-in-law over the phone (he is 700 miles away). He is trying to separate the plastic cover on top of this compressor. He says the attaching screws are recessed and he can't really see which screwdriver to use. Whatever he has isn't working and he doesn't want to damage the screw heads.

The parts breakdown gives a screw part number of "E106614".

On this 921.165720 compressor can someone please tell me what type and size of screwdriver to use on the cover screws? Thank you.

Thank you for your quick reply. When I saw a picture of the screw I thought it was a "torx" head myself. He is away on business for 3 weeks, but I'll tell him to give it a try with a torx tip when he gets home. He said the screw head was recessed, so maybe he just didn't get a good bite angle on the screw head. Thanks, again.

Your son-in-law won't be able to remove the two lower left side screws unless he can find a really long T20 screw driver. I just solved this problem with a trip to my ACE hardware store. Purchase the screwdriver bit #2135267. It's 3.5 inches long so it will need the magnetic bit holder 1\4in. shank #2135168. Both ACE brand. I went to Sears first, but they were unable to help. Vet's Hardware in Lansing Michigan is the best hardware in town!

Thank you, Mr. Brailey, I will pass on this information. I truly appreciate this information, as not being there to see what he's up against makes it difficult to help.
