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

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. :)

Nice quality parts and fast shipping also priced well.

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

This is an upgrade to the OEM knob on my Exmark commercial mower belt cover. Strong and stays in place. Large size allows more torque.

Sturdy and well made -- would purchase again.

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

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

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

As I said, they do the work
