Needed these for a project and they work well

These are a great set of knobs at a good price. Feel really solid and look well made. Worked perfectly for what I needed them for.

I needed some knobs for easy removal and adjustment to my custom canoe seat and these were perfect!

Not bad for the price. No complaints.

Good quality, I bought these to replace some knobs on a bike rack. I cranked these down tight and the quality and durability will last a long time. I would recommend.

Exactly as described, solid construction.

just what I needed for my paddleboard j hooks. These are much more comfortable than the original ones.

Worked great

These star knobs are just what I needed to build several woodworking jigs. I used them with 1/4 inch T-bolts and washers. Good price and works great.

Works great with 1/4 metal screw
