Good news is that these do fit the track bolts I have, but these knobs are a little smaller than I thought they'd be since I didn't really measure the size of my other knobs, which are much larger. They still work, and can be perfect for some applications and are as advertised. Just make sure they're the right size for what you want.

I ordered these for a drill press table I was making. They are much smaller than I expected but they do the job. Description claims they are 1.2" high when they are acually 0.5" high. The low profile has its advantage where the star knob will fit under a clamp and still be reachable. They provide enough clamping power for what my drill press table needs.

Purchased for 1 Project and quickly found another use. I had misplaced the wing nuts on my Tumler's Tumbler and used these since they were the correct thread size. I will continue using them rather than the wing nuts since they are easier to tighten. The materials and construction are first rate and I will buy some more to have on hand.

I used these to make threaded knobs for a Black and Decker Workmate 400. They were perfect for what I used them for, but they definitely are smaller than what you might expect for a 1/4-20 threaded knob. Make sure you check the measurements in the product description before you decide whether or not they'll work for your project. The table top in the attached photo is 1 3/4" thick, to give you a reference point for the size of the knobs.

They work fine and meet he specs, but I find them too small for heavy clamping. They are hard to grip when a large pressure is needed. That said, I have used all that I have bought for light weight projects.

Quite reasonable you need a 1/4x20 knob. Not too thick, but substantial.
