I have 2 bolts on the over arms of my Clausing 8540 Horizontal Mill. I thought at first they were Torx T-60's but I bought one and it is too small. It looks just like a Torx head but has about twice the amount of teeth for the bit to go into. Anyone have any idea what type of bolt head this is? I called Clausing and they said they did not know? I checked the manual and no luck either. It identifies them as 1/2"-13 nuts??? Apparently Torx only goes up to a T60 so it has to be something else. Thanks, Steve
