Review for GDFYMI Star Knobs Thread Screw, M4 M6 M8 Combo Set for Umbrella Base Screw Replacement.I got this set to have a few extra clamping knobs. You get M4, M6, and M8 threads. Each size has a shorter length and a longer length. You get 5 of each size, for a total of 30 clamping knobs. (So you get a 5 shorter M4 knobs, 5 longer M4 knobs, 5 shorter M6 knobs, 5 longer M6 knobs, 5 shorter M8 knobs, and 5 longer M8 knobs.)The plastic handle is light weight. I am not sure how much force these knobs will take when you tighten them.I dislike that the black plastic knob is a bit scratchy on the bottom edges. I don't like having my fingers scratched up when I am applying pressure and torque to tighten a knob. I feel like I should be wearing gloves when I tighten these knobs to protect my fingers.The quality isn't a good as some other knobs I have ordered, but if you want a variety of knobs to have on hand "just in case" something breaks, then this set gives you a variety of sizes.

If you need an assortment of star knobs, this might be what you need. The knobs seem to be of good quality and there are a range of sizes. I like to have these on hand for making various jigs, and since I never know what I’ll need ahead of time, it’s more convenient to keep an assortment. There were no obvious defects in quality.
