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

good stuff cant go wrong with this one. THX

I have Bennington Pontoon Boat, lost one of the tighting handles for the Bimini top, worked perfect. I know the dealership would have stuck it to me. Next day deliver, five, used two, rest are in the boat as back up. Super deal

Strong plastic and brass screw inserts seem pretty sturdy. So far pretty awesome.

Used these as jig hold-down knobs. Worked perfectly.

Sturdy, as described, good price.

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. :)

I used these on a 20 inch high velocity fan that had broken/missing knobs. My fan had fine thread bolts sticking out for the knobs so I just replaced the bolts w standard thread ones and knobs work perfect.

I was having difficulty tightening the wingnut holding my rolling frame I use for cross stitching when My husband suggested looking for something easier on my hand. These work perfectly - you use your whole hand to turn it instead of just a finger and thumb. Works great!

Nice quality. Sturdy. No sharp edges.
