Review: good bolts - These bolts work well and are not soft or brittle like many cheap bolts are
Review: Worth waiting a day or two to get the parts - I got more more parts than I needed at a better value without having to search through bins. Its a lot easier to find coarse threaded bolts that are not fully threaded locally but sometimes its better to let the USPS spend the money on the miles to deliver. I put the leftovers in my bolt bin for the next job. In the long run a better savings of time and money all around.

### ⭐⭐⭐⭐⭐ good bolts
*by G***B on 17 April 2026*

These bolts work well and are not soft or brittle like many cheap bolts are

### ⭐⭐⭐⭐⭐ Worth waiting a day or two to get the parts
*by O***Y on 23 September 2024*

I got more more parts than I needed at a better value without having to search through bins. Its a lot easier to find coarse threaded bolts that are not fully threaded locally but sometimes its better to let the USPS spend the money on the miles to deliver. I put the leftovers in my bolt bin for the next job. In the long run a better savings of time and money all around.

### ⭐⭐⭐⭐⭐ Used these in my Startech 42U rack
*by C***O on 14 September 2023*

I have a full size, 42U Startech IT equipment rack. It uses 8mm bolts and washers to hold the pieces together. The rack didn't come with enough bolts, so I bought these and they worked great. Faster than going through the manufacturer to get missing hardware shipped. There are some situations where a bolt with a separate, free-spinning washer is desirable, but in my case these worked great. Threads on the bolts were cut well and finish is good too. Happy with these.
