Update on Mystery Bolt from Clausing 8540

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, DoN.

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.

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.

Ill be damned. Thanks Ned! First time Ive paid much attention to those.

That's it Ned...Thanks -Steve

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.

Try a 5/15" bolt
