Taytools770405 Lot 10 Each 1/4-20 Female Thread Tri-Star Knobs 1-1/2 inch Wide by 3/4 inch High with Solid Brass Through Inserts

These fit perfectly & are just the right size for hand tightening. Sturdy & a great value for the price.

I drilled holes on the four corners of a wood panel, screwed in threaded inserts and attached four extended thread screw feet through them, so that the thread protruded on the top side. Screwed on a small lock nut and then 4 of these knobs on top, tightening the lock nut against the knob. Viola, I have a height and tilt adjustable worksurface.They are sturdy knobs and nicely contoured to the hand.I recommend them.

I prefer these three lobed knobs over the five lined knobs for my application. It's easier to tighten with three fingers than your slippery palm.

It's the right size and did the job.

I needed a knob to replace a lost one on my Greenworks Weed-wacker motor. The Greenworks knob and bolt have an off camber non-standard thread which will not work with a 1/4-20 nut, so I had to replace both the knob and the bolt.Good fix, threw the other 9 in my drawer. However, I keep pulling them out for other projects where I need a hold down or quick loosen knob.Good quality item, holds up well.

I use a lot of 1/4-20 studs and knobs for work holding. These have held up great. I was so impressed that I bought a second bag too.

I have used Taytools knobs in the past and as are these, they are very good quality and extremely durable...BUT these measure 7/8" from center hub to outer wing which makes them 1-3/4" knobs and they are 7/8" tall. These are great knobs, no doubt, but unless they sent me the wrong ones, the description is in error. Taytools does make a 1-1/2" knob, which I have ordered before, but in a four wing, not a three.

I have a car-top carrier that came with shallow u-bolts to attach to a roof rack. My Xterra has thick, round cross bars so I had to make some new u bolts out of quarter-inch steel bar. I use these inside the box to secure the u bolts. Had some thumb screws that did the job, but these are taller, so they hide the tops of the u bolts better. They are easier to handle and the plastic surface covering the ends of the u bolts is a lot nicer to the stuff I put in the carrier, and that's all I wanted. I'm happy. They do what they are supposed to and haven't failed in any way after some long road trips and off-road camp outs. If I just needed one or two, I would pick them up at the hardware store, but I needed 8, plus a couple spares, so I saved some money buying these.
