Update on Mystery Bolt from Clausing 8540
 

I took the fastener off of the Clausing 8540 over arm and it is
actually a nut and not a bolt. It looks to be either a 1/2-13 or 5/8-11
thread and the top of the nut looks like a SHCS. However, the internal
pattern looks exactly like the inside of a 12 point socket. I have no
idea what this nut is called or where to find the appropriate bit or
key to remove it properly. Any suggestions would be greatly
appreciated. Thanks, Steve

Have you *tried* using Allen keys in it? It may simply be
designed so you have more options of how to orient the Allen key.

Good Luck,

That has crossed my mind and I am going to try that, however I do not
think that is the case. Right now I do not have an allen wrench big
enough for the nut. I would say it will take an Allen wrench at least a
1/2" across. Thanks, Steve

It's an Allenut...

A regular hex key will fit.

Try a 5/15" bolt

The head of a 5/16" bolt might be a better fit and cheaper, too.

You need a 1/2" hex wrench, rather hard to find.

Harbor Freight has a long set in a metal box containing this size.

Ill be damned. Thats a "star" fastener. Have you tried an allen
wrench in it? Often times they will fit, the same way a 12pt socket
fits a hex nut.

1/2" it is, at least on mine..hummmmm

Pause.....

pant pant..back now..

I just went out and checked mine and its just like yours and yes, a
1/2" allen fits. Id never noticed mine before being this way, as the
allen always fit just fine. If you are short an allen wrench, simply
stack a couple nuts on the appropriat sized hex bolt, and use them to
turn the head of the hexbolt, which is inserted into the fastener.
Sometimes a tiny tackweld will keep em together if its really tight.

It sounds like a spline drive. A Allen will only round it out. We use
Spline type in aviation.

Get a twelve point bolt and screw on an double set of nuts. Invert the
bolt and put a wrench on the nuts. YOu could tack weld the nuts if the
slip. THose type of nuts are used where minumum clearance for a wrench
is available and maximum strength is required.
The are commonly used in aircraft as well as other applications. An
allen wrench should fit the nut too but it is only driving on six points
and may slip. I believe I have some twelve point drivers for them but
nothing as big as 1/2 inch.

ITS PROBABLY A SPINE FASTENER. YOU CAN GET THOSE TOOLS
AT SEARS LIKE I SAID BEFORE.

GO TO SEARS AND LOOK IN THEIR AUTOMOTIVE TOOLS SECTION.

THEY PROBABLY HAVE WHAT YOU NEED.
