The next time you are in need of a thumbscrew for a jig or a clamp, try an eye bolt with a machine thread instead of buying more specialized hardware. They are available in various diameters and lengths and, when used with a T-nut, they have great holding power. The loop in the bolt allows you to apply plenty of force — just with your hand.
