Woodyah has reproduced a small screw with the 10-28 threads. These are sold as SINGLE SCREWS. These are very commons threads used by Stanley and many other manufacturers before there were screw thread standards. You cannot get these screws in hardware stores. The length is 3/8th on the Thread. These fit hand planes, spoke shaves, scrapers, plow planes. If there is a specific tool just ask. the photos show some of the common tools. But that is not the complete list.
These are my very own screws with my very own head that I designed. As a tool user I know what works and what causes me frustration. This offers a slotted head so you can really tighten the screw. Also with knurling to allow you to get a good grip. I like these screws on my bench planes as I enjoy them more than the common thumb screw, Reach out to me for compatibility or use google as I would. They also turn smoothly.
