Strange tool
dick hines
This nothing to do with turning but I bet there is someone on the message board that can help. I am looking for a tool that looks like a star. It has 8 points. I need it to repair my show trailer. The two big box stores close to me do not have anything like it.
HELP!
Spider drive

or 8 point torx is probably it. Standard torx is 6 point... I think.

I tried looking this up, perhaps this is a double square drive.
A post on a forum mentioned trying a square bit to engage four of the points, if you have a bit of correct size.

Just a wild idea: I have made special tools in sizes that I needed and could not find or get quick enough. Often a grinder is all that is needed but for a star-shaped profile I suspect a thin metal-cutting disk on a dremel would do the trick. I might either measure the screw/bolt or make an impression an then a template. Or just make it by trial and error.
A good thing to start with might be a hardened hex bit made to fit a 1/4 or 3/8" square drive.

Hi Dick , It is usually known as a double-square bit, commonly used in high-torque applications such as axles. Many German manufacturers use them on driveline applications.

I could not find the double square tool sooooo. I bought a square tip tool. And guess what it worked.
