Today's Weird Question

I have seen flly threaded studs with a hex head opening in one end so that you can tighten them down with a hex end wrench.  Do these have a special name?

Apparently they are sometimes called "grub screws".

RevGreg: awesome, grub screws are close but probably not as useful in this context.

Internal set screw - aka grub screw on the island formerly known as Great Britain.

An external set screw would be fastened externally - a slot or hex head; internal set screws have the recess for a hex, torx or tamper-proof torx or other similar wrenching system.
