Quality made product. Threaded rods were securely mounted in knob at a perfect 90 degree right angle. All knobs were smooth and functioned as intended. I would not hesitate in future purchases.

Ordered these 10 pieces of 1/4''-20 thread plastic star-shaped knobs for a project, and they’ve worked out great. The knobs feel sturdy and are easy to grip, making adjustments effortless. The clamping action is solid, providing a secure hold without any slippage.I’ve used them for various DIY projects, and they’ve held up well under use. The quality of the plastic is good, and they’re a perfect fit for any project requiring these sizes. They make tightening and loosening quick and straightforward. Definitely a reliable addition to my toolbox.

I got the 1" bolts, and they are actually longer than I expected them to be. I think they used pictures of the shorter bolt for both options.The description says it's a replacement knob for an umbrella base, and I think they would be ideal for that. I have a couple of umbrella bases on my deck, and I may eventually use one of these for that.But I bought these to make woodworking jigs in my shop. I have a couple of small jigs that I plan to make in the next few months, and these will be perfect for them.As you can see in my pictures, the 1" bolts are longer than they look in Amazon's pictures. I show one of them up against a piece of 3/4" plywood, just to show that you have plenty of length to go into a T-nut or threaded insert in the board below. In fact, I included a picture of the bolt up against the side of a piece of plywood, with the end inserted into a threaded insert, to show that it would work fine. And if your jig uses 1/2" plywood (like mine will), there will be even more threads showing out the bottom of the board.Yes, the knobs are a little small. But that's okay if you aren't going to be tightening them as tight as you possibly can. They're plenty big enough to snug your work down.I highly recommend these, if you're going to be putting together a small jig or two. I'm glad I ordered them.

When I was younger and had no money I had to make knobs. I used to keep the plugs from the hole saw To fabricate makeshift knobs. While they were already round and had a perfect hole right in the center they were fat and sometimes interfered with what I was trying to adjust.I have no immediate plans for these but I do make a lot of jigs because they are unique and buying them can be expensive, and I have plenty of time. The knob is a good size and I chose a 5/8" --1/4"-20 bolt.Cheers

Pros:- Decent build quality- Standard ¼-20 camera thread size- Fits DSLR well- Versatile for various home projectsThe Xadnitu ¼-20 1†Screw Knob (10 pcs) is of decent build quality. It has a standard camera thread size of ¼-20. It fits my DSLR well. However, the 1†screw is probably too long to secure a camera to a bracket.Unfortunately, all the knobs are identical and I wish there were shorter variants. In hindsight, a ½†long screw would probably be a lot more useful for camera use. However, it is not the fault of the product. I should be able to cut down the length of the screw to make it more camera-friendly. Nevertheless, the screw knob is very versatile and should be useful in many home projects.

I use 1/4"-20 threaded knobs for my woodworking jigs. I saw one reviewer commenting that the knobs are rather small, but that is what I have been looking for with one of my jigs. At $1.10 per knob, these are a good deal.
