Help! I have a 1/2 inch drive Kobalt torque wrench that is missing one of the two small screws that attaches the ratcheting mechanism cover plate to the head of the ratchet. The plate came off, and I was only able to find one of the screws. They appear to be very specialized (uncommon) with a Phillips head. Any idea where I might search for such a specialized screw? I have had the wrench for about two years and seldom use it. I hate to scrap it for lack of one small missing screw. (The salesman I talked to at Lowes was of little help.)
