Q. There is a position for an earth connection that looks like it is meant to take a self tapping screw. Can you tell me what size the screw should be?
A. Hi Steve. Thank you for your question. These have a 2mm hole but does not appear to have been threaded, so you can either tap out to the size you want or you can use a 2mm nut or screw. The only 2mm version we have to offer is a bit long at 10mm but I have a 33-2210 as the best I am able to offer.
