Help Identifying Bolt
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 |

Thanks, Steve If you are talking about a bolt with a head like the end of the Torx wrench, not the socket, then it may be akin to what I have seen many times on high-vacuum systems (made and sold by Varian). The bolts were stainless steel (to survive the bakeout process without rusting), and had a head which fit a 12-point box wrench. There was a shoulder on the head to keep the ring of the wrench from contacting whatever was being bolted. The ones which I saw were smaller than yours, with 5/16" thread being the biggest, with 1/4" being the other size, but I suspect that such heads are available in larger sizes and other materials. I suspect that these were not the *original* bolts on that machine, and those would be more likely to be Allen style SCHS or even pure hex heads.

Thanks, Steve Could be triple-square, if someone has installed metric bolts. 12-point, come in lots of sizes. http://www.sjdiscounttools.com/kd2304.html Dale Scroggins |

I have the manual and the mill (sorta) so I can check here given that info. If these are the two bolts on the top of the housing that are used to clamp the two overarms in place, they *should* be standard SHCS. |
