Review on High-Quality Off White Slotted Length Threads for a Perfect Finish by Elvis Kimbro

Unlike the picture, the slot for the screwdriver is a small recess. At first I couldn't see them and wanted to send them back as defective. The slot is so small that a jeweler's screwdriver is required. That's why I put an asterisk. I have a size of 8/32 x 1 inch. I can't tell you anything about other sizes. I've found that I can easily make full size slots with a small hacksaw, or I can just use a jeweler's screwdriver so I keep them.
