The part number 21-1860 shows up plainly in our catalog with this exact description, thread, and length, so you can order with confidence that you're getting the correct screw rather than guessing off a general hardware bin.
If you're replacing more than one, it's worth pulling the old screw out and comparing length and thread before ordering, since gearbox cover screws can vary in length by position on some models. Give us a call if you're not sure which one you need.
