### ⭐⭐⭐⭐⭐ A must for every shop and hobbyist.

### ⭐⭐⭐⭐ Does the job for good price. Recommended
*by H***R on March 19, 2026*

I liked these ok. Everything you need here. On chain won't lose them. The "bad" is the threading isn't the best I've ever seen, some rough. But usable. The "good" all on a chain so don't lose them & all in one place for all sizes A few burrs but easily fixed. I recommend this product. They work great. At good price. The metal is dry so a little. Vasaline or light oil on the ones u use makes it easy to use. I'd buy again & recommend good price
