15Pcs M4 7 Star Through Hole Knob Female Thread Nut Clamping Knob Grip Assortment Kit, Star Shape Hand Knobs Black Plastic Screw-On Handle Clamping Knob for Mechanical Equipment (M4)

These were phenomenal for my intended use. Works very well with grid walls and so much easier than fumbling around with the screws and nuts I was previously using. More durable as well!

works

Used these for making a pet wheelchair. They’re great for making it easy to adjust the wheelchair.

Got for my Tyger tonneau cover when I accidentally stripped the hand knobs that came original. No complains and its been several months of use.

The confusing description indicates an "assortment" of through bolt female star knobs. It says "Head Diameter: 25mm(1""); 30mm(1.18""); 37mm(1.45"")." The 15 knobs I got are all 25mm. That works for me, although I could have used a few wider knobs.

Great value

I had lost two of a similar, but different knob and really wanted a good replacement. This is a great product. It just took too long to get shipped

I do wonder who needs 15 of these. I needed one and now have 14 spares :-)
