  • I couldn't find any of this at the hardware store.
Size: 580Pcs M2-M5 8mm-20mm
I love this set. I won't need to worry about finding the metric size nuts and socket head screws. I wasn't able to find what I needed at my well stocked local hardware store. I needed to replace a socket head screw and nut on my bandsaw. Without finding the correct size, my next option was to replace an entire bearing mount for a hundred dollars. This saved me money and I have plenty of spares. ... show more

  • NINDEJIN M4 362 PCS Hex Socket Head Cap Screws/Bolts Nuts Assortment Kit
Size: 326Pcs M4 5mm-20mm
362-piece M4 screw kit spans 5mm to 20mm lengths, made of 12.9 carbon steel with black oxide finish. Fully threaded, Allen hex drive grips tight—no stripping noted. Nuts match perfect, tho smaller sizes can cross-thread if rushed. Organized plastic case keeps sizes clear, but lid’s flimsy, pops open easy. Rust resistance holds up in damp settings. Solid for DIY or pro fixes, tho case could be tougher. Weight’s manageable, great spread of sizes. ... show more

  • Precision Threads ~ Resists Stripping-Out ~ Built to Last ~ Free Tools!
Size: 326Pcs M4 5mm-20mm
What I like: The threads are high precision machined; not a bad one in the bunch! The product resists stripping-out. High Strength and built to last. I was delightfully surprised at the good quality of the included Hex wrenches, as typically such included tools are cheap and prone to easy bending and failure. What I don't like: I can't find anything to complain about. I'm confident that I'd order this item again. ... show more

  • Good set
Size: 326Pcs M4 5mm-20mm
I'm not an authority on this type of thing to be completely honest, but to me this seems like a fine set of hex screws. They all are the same size but come in different lengths and a large amount of nuts, presumably enough for each of the included bolts. Very easy to use, the package includes two Allen wrenches which are strong an equal quality to ones you would buy separately. All of the bolts come in individual plastic baggies inside of the box it includes to keep them in and there are spacers to keep all the different sizes / items divided, though I chose to leave mine in the plastic baggies as I am bad for dropping things and then that way if I do ever let it hit the ground not that big of a deal as they'll be very minimal mess and no confusion or time-consuming organization back to the original storage areas. I think it's a good box of nuts and bolts at a fair price. ... show more

  • Bolts for everything
Size: 326Pcs M4 5mm-20mm
This is a good selection of strong bolts and nuts, and the case is great for keeping these organized. I used some of them to attach a loose front license plate on my Forester which was flapping in the wind with only 2 top bolts when I bought it. I had to drill the holes into the bumper, and now the plate is secure so it won't bend. ... show more

  • Average quality
Size: 146PCS M6 8mm-30mm
The bolt is stamped with 12.9, which means it is made of alloy steel SCM435 (I'm guessing, which the harness is around 38-43 HRC); and the tensile strength is 1,200N/㎟, the proof stress at 0.2% which is Yield strength 1,080N/㎟. All this means that it won't break up to 1200N/㎟, and if tensile is within 1,080N/㎟ it will remain its flexibility to return itself into original state after being stretched. The surface treatment is black oxide, the material is structural alloy steel (SCM435) which hardness is around 38-43HRC. These are high-strength fasteners, well suited for machinery and heavy duty application. However, they will rust in damped environment. Judging by the stamped number poor legibility, I find it a bit pricey. ... show more
