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

size of knob is perfect however I would prefer a 1/4-20 thread as this size fits all standard t tracks

Knobs spin nice and easy on the stainless bolts that I have. These were hard to find in stores so this was nice and convenient. Wish they came in different quantities but otherwise a solid product for the price. Hope they will hold up being outdoors! Will report back later if not

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

These knobs are well-made. Large star shape provides excellent leverage. Threaded brass insert is imbedded securely in the plastic knob.

Well made will buy again

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

Just what I needed. Using these on woodworking jigs, have been great..Cheap too.

I bought these to secure my drift cutters on my snow blower. They are the perfect size (about 2 in diameter) to both get them very tight, and to grab and use with gloves/mittens in the winter. (For those not familiar, the drift cutters are normally stored in the down position against the blowers auger housing. But when there are huge drifts of snow, they are flipped 180 degrees into the up position . These knobs let you switch between either position quickly, and with no tools. :)

Happy to do business with USA manufacturer

Great for holds for my cnc
