Openfly 28 Sets Star Knobs Thread Replacement Star Hand Knob Tightening Screw Clamping Screw Knob Quick Removal Replacement Parts for Umbrella Base, Swing Stand, 4 Sizes

Replaced the lost stand knob on my powered speaker with spares included at a good price.

It’s slightly rough around the edges and can actually be a bit discomforting when tightening them. Over than that it’s amazing.

I only needed six knobs out of the set the 4 8mm and only two of the 6mm. But it was cheaper to buy the whole set than it was to try them by them individually

My new umbrella didn’t fit in my old stand because the screw was too short. The package gave me the perfect size to make it work

Thank you.
