Review: Handy for odd jobs.....But - Really good and handy set, they feel decent and well made for the most part, no sharp edges etc. Good selection depending on needs. My only slight gripe is that the nut tolerence is a little loose so will limit torquing down, make sure ye use a crush washer if placment has potantial to shake loose.

### ⭐⭐⭐ Good selection….but
*by F***T on 2 February 2024*

This set of nuts and bolts is pretty good for the price. There is a good selection of sizes within each diameter thread. Unfortunately what lets it down is the organisation of the nuts and bolts. Instead of each bolt, nut and washer having its own compartment, some of them are mixed together with another. So it can be tricky to get the bit you need.
