IC Core Hole?

[valentin_84]

Hey guys, I was workin on picking this IC Core lock today and I was wondering what the hole drilled into the side of it was for? It doesn't seem to give me any access to anything but I'm pretty sure it's factory drilled because the threads on the side are still perfect and working.

Doesnt appear factory to me. Hard to say, it is threaded?

Um, it slightly looks threaded but I originally just thought they were the marks left from the drill...

Kinda looks like someone drilled out a bolt hole. The mortise cylinder screws into the lock body which is mounted in the door itself. Depending on what hardware was on the inside of the door, be it a thumb turn, it should mount as a cylinder with a cam also. This looks like someone tried to mount something it to the back of the cylinder via screws. Again, it looks like it was drilled to me by someone other than the factory.

I can practically confirm that it is factory done. Based on the fact that I've seen that threaded hole several times before.

Unfortunately I can't tell you which locks use it.

Maybe an alternate set screw point?

That's what I always thought when I saw these in the wild. I have several that have the hole, always drilled at a very odd angle into the lock.

Yes that is what that is. +1

My dad said the same thing at first but the hole is so big and it runs so deep that we weren't sure....

Well thanks for the help guys!

A pointed set screw is started from the inside of the open hole in the cylinder (it's a bear to get it started while in the door) before the lock is installed. once the normal set screw of the adams rite assembly is tightened, then this set screw is tightened and the lock is much more resistant to tearing it out of the threaded lock assembly.

Since the setscrew is recessed, it does not hinder the removal of the cylinder by the control key.

So your saying that while the core is out, you drive a screw from the inside of the lock to out and into the door?

Yes, while it's in your hand before installing the cylinder, just start it a few threads and then once the cylinder is installed, you finish tightening it from the IC core side and then install the core.

Another benefit of this internal set screw is that someone cannot remove the cylinder without first removing the core. A very nice security feature in addition to the enhanced wrenching/tearing protection. It's a shame this is not used more IC cylinders.

That makes a lot of sense guys! So, what screw goes with those threads? Does the screw come with the lock or do you just hunt till one fits?

It's a unique pointed hardened setscrew about 1/2" long. Easy to install, provides more security, and is often not understood and therefore left out...
