I have an oak adjustable threshold that I believe was manufactured by Pemko. One of the adjustment screws is damaged and I'm trying to figure out how to replace it. I contacted Pemko and, as I expected, they were no help. I have attached pictures of the threshold and the adjustment screw head. The screw head is a philips screw and the shaft of the head is splined to attach to the actual adjustment screw. If anyone has any ideas on where I can get a replacement screw head I'd appreciate hearing about it. Thanks.
I don't know where to get a new one, but you can make an adjustment right now by borrowing one of the heads from the working outboard screws and drop the stripped one back in the hole as a non-working plug.
