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

Needed these for a project and they work well

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

Nice quality. Sturdy. No sharp edges.

Added to sailboat hatches in place of wing nut. Excellent material well built

These there here knows there will get you where you need to be, but the plastics used is cheap and will crack with relative ease. Seriously though, use these for lighter duty applications, or they will fail. I used this product for a folding handle on my push mower and you really have to be careful with how tight you get these. Worth a try for most things, return if they dont work out!

As I said, they do the work

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

Used these to replace dog knobs on a gray enterprises port light on my hunter 25.5 sailboat. Worked well

Knobs were delivered timely.
