Where do I get bit for this screw?

[Randall Clark]

I am trying to remove some 40 plus year old cabinets, and I at first thought that the screws needed were square head. Upon closer inspection, the screws appear to be a rectangular head bit to remove them. Have you ever heard of this? Where can I get one of these rectangular head bits?

[Ole Anderson]

Could you just file or grind an old flat blade screwdriver to the correct size?

Check at a mobile home supply or RV dealer. They used a screw that was a bow tie shape and that is the only place I have been able to find them.

It's probably a Robertson Drive.

The OP stated they were not square.

If McMaster Carr doesn't have it, you'll need to grind your own one.

Robertson drives seem to be square head. The ones I am seeing are rectangular.

[Ron Natalie]

I think OLE has the right answer and that was probably how they were installed to begin with.

[Steve Kohn]

What you're holding is not rectangular if I'm thinking correctly. The sides are slightly concave. I believe if you look for a security screw bit set you may find what you need.

I a bought a socket from Snap-On several years ago that fits that type head,if I remember correctly it was a special socket for Chevy trucks.I have been looking for the socket in my tool box but I have not yet found it.If i find it I will pass on the part number.

[Jerrimy Snook]

Looks kind of like a clutch head.

[Mac McQuinn]

I have not seen these in a while although we use to call them cam drives. I believe I still have a driver for these which fits a 3/8" ratchet, I'll check.

I have been watching this thread with absolutely no input just interested in where it was going to lead, but I have to ask, HOW in the world did these end up being where they were. Were the cabinets kitchen cabs or were they from something else?
