DCT 5 Star Knobs 5/16in-18 Internal Threaded Knob Clamping Knob Jig Knobs – T Knob Plastic Knobs, Threaded Knobs 5-Pack

Works Great - Very Simple Item - Hard to screw it up.

I used these to attach my track boards to a roof rack. Worked like a charm, shipped fast, and not too expensive.

These look better than expected. Brass through hole is threaded .61 (15mm) deep/long inside. They snug down easily / well.

After educating myself, as to the pitfalls others wrote about other brands of star knobs, regarding defects or poor design, I picked these Star-Knobs, to complete the miter saw table. Most likely, since youre reading this, you know what theyre used for. In my case, theyre for tightening down the stop blocks on the miter saw table. They dont have any parts that might fall out. And,at a quick touch of your finger, you can spin them all the way till it hits the tightening point. Not much else I can say except; Good product. Nice looking. Price is right.

Nice quality. Sturdy. No sharp edges.

Brass inserts

Nice quality parts and fast shipping also priced well.

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.

VERY PLEASED !

Just what I needed, used for a flip top bench for my drill press
