Knurled M5/M6/M8 thumb screw

I needed some thumbscrews and didn't like any of the existing designs so I created my own. It covers the top of a hexagonal bolt turning it into a thumb screw. Available in 3 sizes: M5, M6 and M8. Consists of 2 parts - the main body and a cover that is friction-fit at the top. You can add a few drops of glue if you want to be extra sure the covers stays on top but it's not a must.Changelog2025-05-28: Added M5 and M8 models I created for my Nuts and Bolts Toy for Toddlers.
