515-Piece M3 M4 M5 Metric Socket Head Bolt Set with Stainless Steel Screws and Nuts

eric: Has most of what you might need when you start ripping into/modifying 3d printers. Would be nice to have M2 screws and locking nuts.

Kyle Brey: I love this kit., love it.
I've been in the process of swapping out all my cheap "chinesium" bolts for these and have been pleasantly surprised by the quality. Out of maybe 35 bolts so far - zero have had thread issues and only one had a poorly stamped hex, which for a kit THIS big and this cheap, is amazing lol!
The case is top notch! 3 separate hinges keep the lid tight. Not crap plastic snap hinges either, these are real 2 piece hinge locks, as well as the lid to case hinge - 2 piece with metal connecting Rods.

Each bolt/nut type is individually bagged which is a major major plus! No worries having to re-sort everything because of rough shipping!
The dividers are good quality and strong. I hot glued them to the bottom for added security but, honestly, it isn't needed.

Even with the few "negative" points I've reviewed below, I'll purchase this kit again if/when needed. I'm really hard on my rc trucks so I'm sure I'll need more, maybe not though as these are quality pieces. But for future builds, or when need arises? Absolutely would buy again!
I'd say 4.5 stars, really and the biggest reason is the largest size bolts/nuts most hobbiest won't use BUT...

Austin V. Hearell: I'VE ONLY USED A FEW OF THE 4MM FASTENERS SO FAR. QUALITY OF SCREWS SEEMS GOOD. REALLY LIKE THE CASE. PROBABLY BEST CASE I HAVE EVER SEEN JUST FOR A SCREW ASSORTMENT. EVEN AFTER I USE UP THE SCREWS THE CASE SHOULD BE GREAT FOR STORING OTHER SMALL ITEMS.

CB/PDCB/PD: You can see the button cap on some of the screws is not perfectly true, but the position of the hex-tool point IS straight. So essentially you are getting some great quality hardware with no perceptive visual flaws. Meaning, the only way you can tell any of these screws are not perfect; Is during the spinning/installation. Also take not that most of the hardware is perfect! So far out of roughly 50 screws used, I have only come across one screw with a failed hex punch on the top, making it useless; but I expected that at this price.

On another note!

The quality of the container of this hardware set is actually astonishing. 3 different hinge clipping latches, individually slotted spots for each part as seen in their stock photos; each set of screws comes in a baggy... and to top it all off; the container has a nice thick silicone O-ring seal.

You really can't go wrong with this hardware for the price! I would recommend to anyone who wants cheap, good quality hex screws. I can't attest to their strength under extreme tightening conditions; as the RC hobby I am using them for does not require much more force than 25lbs on anything.

JefferyS: The screws are great, seem to be good quality and a nice selection of what I needed.

The box would be awesome but the dividers can come out easily which can make a real mess. They should have made the slots where the dividers cross much smaller as to make a tighter fit. the slots on the edge of the box could be smaller too to make it sit in there tighter but otherwise okay.

I do like that all the different pieces were put in their own separate bag, otherwise it could have been a real mess during shipping.
