The description on the product set 20 pieces. When my package arrived, there was only 14. Be aware that you're not getting what is described

These are made well and I have no complaints. They fit all the holes I have shoved them into and cost me nearly nothing for the pleasure. I have screwed for far more than this and at least this time, I am satisfied. I am dysfunctional but these function with ease. LOL.

Was 2 short and didn’t notice until I got the rest on and the only way they would refund or send any more is for me to take back off all the bolts off and send them back. So I just took the loss. They fit tho.
