Innovative Components AN4C-5S3A-21 1.75" Star Knob thru hole 1/4-20 steel zinc insert black pp (Pack of 10)

With a 1/4-20 insert and a larger Counter Bore allows this to be used in multiple ways! I'm using a #10-32 screw with a standard washer and found it easily adapted to my application. Slight deburring might be needed to remove some sharp corners, otherwise the form factor is good. So I'm attaching the knob to something with a smaller screw, but it can also be used with a stud on your part and tightened down, or used to hold something which can be easily released. Pretty useful!

Great, efficient, sturdy and a great deal. Replaced the OEM Thule finger nuts with these for my kayak carrier.

I used these for a drill press table that I built to lock down the fence, lock down the table on the drill press and for the lock down clamps on the table. They are well made and feel good in your hand. This part number stays loose all the way down the bolt and doesn't tighten as the bolt passes through the knobs back. Some of these that look the same tighten up once the bolt gets to the back of the handle so make sure which type you are buying. I couldn't be happier with these knobs.

High quality. I'm a little surprised how well made these are. I was expecting less for the price.

I bought a package of these knobs after watching a video by Ron Paulk. I knew I'd be making some jigs and such in my shop.As Ron said, these are handy things to have around! I bought three different sizes in anticipation of some projects. That was a good decision. I like the 1.75" and 2.25" knobs better because they are easier to grab, even with numb fingers outdoors in the winter. The smaller 1.38" knob is a winner when there's not much clearance. Of course they work with any 1/4-20 bolt: hex head, carriage, or T-bolt.The photos show two of these knobs in use to secure a Bosch featherboard on my table saw. The shop-made extension on top of the rip fence is secured on the back side with three more star knobs.One photo shows a comparison of three featherboards. I used these five-point star knobs on the Bosch featherboard. I liked them better than the three-point knobs that came with the other featherboards.I like these knobs a lot. They have been VERY handy to have around. They only cost about $0.75 per knob. That's a bargain.I hope you find this helpful.Also shown: Bosch RA1171/RA1181 Feather Boards 2-Pack # 2610927685 JessEm 4016 Feather Board Double Kreg PRS3020 True-FLEX Featherboard, Pack of 2

I am using these combined with some 3d printed clamps and 1/4 bolts to hold down parts on a CNC router. There are no problems with the product other than it is pretty tall and bulky which can sometimes cause clearance issues. Occasionally I have to use a wing-nut instead or find another solution. But in most cases these work just fine.

Great quality at a great price

Nothing much to say except, I've tried them all over the last 45 years of working in my home shop, and these are the best...PERIOD!!!

Arrived on time, as advertised. Amazon asks me to rate Sheerness, not sure what they mean by that in respect to a star knob?
