Swpeet 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)

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.

Great value

These knows are smaller in diameter than I had expected or hoped for. Also be aware that they are metric.

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 :-)

Description states that the base diameter is 16mm, in reality it is less than 14mm, pictures attached.

Spins on beautifully to M8 double threaded rods. Used them to fasten some 2x4 brackets to my utility trailer for a cargo turtle to live on top- great decision since they turn so nice and are of nice solid construction. No tools are needed to tighten or loosen and they hold really nicely to wood. Like star crossed lovers separated by some sturdy 2x4 but instead of letting it get them down they just keep holding tight, close to each other, across a densely packed fibrous piece, forever knowing that the other is there and waiting for them because the stronger they hold, the tighter they feel.Bought a second set since I used them all up for my brackets and I use them for a straight cut jig for my skilsaw, threaded to the ends of the rod and snugging them up again around the piece I’m cutting. Love not having to get the tools out every time.Just for the not-so-savvy hardware folk out there- these are designed for metric bolts. The sizes work out the same between metric and SAE but the threading DOES NOT and if you’re looking for the blissful, silky smooth spin described above you will NOT get it with these, yes YOU who always assumes that what they’re reading can’t be right, YOU will not be able to tap the point and watch it dial itself in effortlessly. So if you’ve listened long enough to accept that they work nice, listen long enough to accept that you’re looking for metric to metric, SAE to SAE. Safe spinning!
