I have a new lawn mower. According to the instructions I need to change the oil before using the mower again (the instructions say to change the oil after the first 5 hours of operation, which is about how long it ran mowing the whole yard twice, which is what I've done with it up to now). The drain plug is in the form of a screw with a square-shaped recess in the outer end. I know that the tool used on such a screw with a hexagonal recess is sometimes referred to as an "Allen" wrench. Does anyone know what the proper name is for a tool that fits a screw or bolt with a square-shaped recess in the head, so I know what to look/ask for?
My experience with those sorts of sump drain plugs is that they typically take either a 1/4" or 3/8" socket drive. The appropriate size extender bar and either a ratchet or a flex handle will work just fine for those.
