  • Grade 8 hardware kit worth having
Having a full assortment of grade 8 bolts and nuts on hand has saved me multiple trips to the hardware store at inconvenient times. The selection covers the most common sizes and the quality is noticeably better than the zinc plated hardware store bins. Everything is sorted and labeled clearly so you can find what you need fast. Great value for serious hardware that you can actually trust. ... show more

  • Finally, some high quality bolts of sort hard to get in local stores.
Been wanting higher quality bolts than I can find at hardware or big box stores. This seems to be exactly what I wanted. Very pleased. I don't have a way to test strength of these but they seem like the real deal. And fit and finish is outstanding.

  • Dees nuts (and bolts)!
If you own a ride on mower it will eventually loose a bolt. My mower is made in America and yet it lost a few! Turns out you need to check those! With this collection of fasteners I can now confidently ignore any loose parts on my mower, and when they fall off I now have what I need to put it back together. ... show more

If you’re like me, probably looking for some “every day bolts” on projects / repairs. Don’t wanna spend a fortune on bolts and not thrilled about going to “big box” to find bolts. This seems to fit the requirements. PROs: They are thankfully well cleaned, nothings more horrible than metal slivers on bolts that are virtually invisible in your fingers, these are honestly good. Zinc plating looks good and uniform. The variety/ assortment seems about right, they put in what I would say is, “normal replacement” type bolts, as in this is what you would find on most vehicles before Metric bolts took over, riding lawnmowers / tractors and most projects that people looking for “bolts” and reading this would probably be looking for. I absolutely love the top cover and inside Bolt Map, it keeps things organized and easy to find. CONs The box is really flexible, I’m thinking of putting some scrap wood on the bottom and just epoxying it on, you really got to “let it be” and open the lid, or you absolutely be picking these things up off the ground. These aren’t for your Space X Raptor engines, the threads are not super smooth on the knife outside edge , they ever so slightly “catch” off and on with an occasional chip out. If you ever worked with expensive head studs or cap screws, you know how nice the nuts fit slightly glides on. The nuts fit slightly loose, as in, threaded half on and you wobble the nut on the middle of the bolt. I personally have no issue using these for lifting an engine, but not on a spring perch. It’s probably just a result of the speed of which these things are being pumped out, I believe the tolerances could be better.. but not at this price point .. , but it’s good enough for the guy in the garage or on the farm. I knocked a star based on the box and loose tolerances. ... show more

I love collecting bolts; you can't have enough bolts. Running to my local hardware is not an option, it's 20 miles away so I have to stock my own stuff.
