6pt versus 12pt...what's the difference?
Sorry to sound so dumb, but I need to order a 7mm and an 8mm open end wrench to work on my Vespa. The tools are available in 6pt and 12pt, but I don't know what that refers too. Is it the thickness of the tool itself? Help! Thanks in advance.
It refers to the number of surfaces inside the socket. A nut has 6 surfaces. You can make wrenches with 12 or 6 surfaces to grip the nut
On open end wrenches there are no points.The wrench you are looking at is a combination wrench(open on one end and closed on the other). Unless your working on bolt that are rusty or in bad condition get a 12 point. This will allow you finer movement of the wrench for working in tight areas.When buying sockets it's best to get 6 point.The reason for this is because ratchets have a geared wheel inside the head of the ratchet that will allow small movements.Your vespa shouldn't have any 12 point nuts or bolts so you would do best with 12 point combination wrenches and 6 point sockets.Be careful not to over tighten these bolts.A bolt with a 7 or 8mm head is a small (4-6mm) shank diameter and will break or strip the threads easily. Good luck !
