Need Help To Identify Key.

Hope14

Hi - Hope someone can tell me what this key was made for. It measures 3&½ inches long. The Bow and Shaft are brass with the last inch being steel. The steel end consisting of the Hex Opening. The Hex Opening measures .360 Thousands, not quite ⅜″, but more than5/16″. ANY INFO WOULD BE GREATLY APPRECIATED. Thanks - Rex

Looks like a clock key to me.

I thought the same thing but I’ve never seen a hexagonal clock key; they are all square, or at least all the ones I’m aware of.

Thanks for info received. I also thought all clock keys had square drive. Some Banjo Head nuts are Hex Shape. Anyone have any thoughts on this? - Rex

Perhaps it’s for turning a gas valve in a very old floor furnace or a fireplace? I recall my grandfather using a key to turn on the heat from a very old floor mounted gas furnace, but the key wasn’t quite as fancy as this. I don’t know if it was square or hex drive though. Still looks like a clock key to me.

Could this be a key for a screw lock?

Hexagonal pins are occasionally used in passage locks, and this may be for this sort of one-sided use.

There is a window lock called Fayle-Safe that used a key like this. Made from around the 1970’s until now, not sure if they have a hex key.

Billy, it appears that the Fayle-Safe wood window lock bolt and key had a round head with a flat on one side, see thumbnail attached. Made by Trileen Mfg. Co., I believe they are now be out-of-business.
