Great value
I needed this size bolts for a project so I went to my local box store and was surprised how expensive this were,I could get about 8 bolts for the same price that I got this box of 50,I really didn't need that many but I couldn't pass this offer,they are the same quality than the more expensive ones,my only complaint is that the box was smashed inside the delivery package ,but for the looks of it it happened during transport because I counted the pieces and they were all there.

Fantastic Price compared to local **** store. Same Quality.
Great bolts! I have used a half dozen or so for projects and found no flaws in any of them. I am using them with t-nuts which I think are a little more prone to cross threading than regular nut and so far every one of them has threaded without any problems. I bought a box of them so probably won't be buying any more for while but when I do and/or if I need a different size I will certainly look to Amazon and the Hillman Group to make that purchase.

Great value!
We use a lot of these and it’s much more economical to purchase these in bulk. Great value for the money.

Count what’s in the box
The box was all taped up when we took it out of the packaging. It was supposed to have 50 screws. There were only 24! Open your boxes and count them to make sure you get 50. We returned and hope replacement is right !

Good value
Buying these in bulk has saved me a lot over buying at Home Depot. Probably 1/2 the cost there
