1440 PCS Nuts and Bolts Assortment, 304 Stainless Steel Hex Button Head Cap Screws Bolts and Nuts Kit - M2 M3 M4 M5 Machine Screws with 4 Wrench for Home Repairs, DIY, and Professional Use

A good assortment of sizes, presorted in a convenient box. The nuts & bolts have well formed threads and the inclusion of allen keys was useful (although a set of cheap, even pressed out spanners would have been useful to most people as the nuts sizes are much smaller than most people have to hand). The box seems pretty robust, closes securely and opens easily enough you don't end up throwing them everywhere! On arrival the parts had remained in the various compartments & not got mixed during transit which isn't always the case. There's a abe on the lid giving the contents of each compartment which is a useful addition.At the end of the day, they're nuts, bolts & washers, if you need them in this size range rather than a single specific this is a good comprehensive assortment with no flaws I can see. The price was good compared to similar offerings and I'm pleased with the purchase.

All threads are smooth and NOT the cheap soft metal type.I used these to assemble the busbars on a Lithium battery that only had 6mm of depth on the pillars so the accuracy of the threads were critical.The set came with 3 allan keys & all nuts & washers needed, both spring and flat.Just as important is the case it comes in. The separation compartments are well fixed and a layer of bubble sheet in the lid stops them all mixing up if turned upside down.All in all a great set and will purchase again on the next project.Please note the photos show the kit after use, so some parts have been used.

I needed a realiable source of M2-M4 screws of varying lengths for a radio control model hobby. It's very hard to guage quality of Marketplace goods - particularly those without a known brand. Having gone through 3 different sets over the last couple of months, I can happily say I've found that reliable source. These screws arrived in a solid and well partitioned latchable box. It includes required allen keys, in addition to useful washers and nuts. Most important of all is the quality of the screws themselves. My biggest concern was the longer M2 screws where I've had real issues screwing into plastic resulting in damaged heads. No such issue with these. Many thanks for the great product.

i was looking for a while for hex socket screws, that had a big variety of different size ones. for a DIY project in my home. and came across this one. Really helpful and sorted by size in big compartments unlike other packages that i have got. and ended up being a mess for when they got delivered.

Amazing for its price

I was looking for a set of screws and nuts to use in 3D-printed models and electronic enclosures, and this set is absolutely spot-on. It is high-quality and sturdy. The selection of pieces is great; the hex socket head feels sturdy and high-quality - I definitely prefer it to Philips heads; the box is really good for storing the screws and nuts. Definitely recommended!

I've bought this set of screws for my 3d printer. Original screws were made from cheap steel and head caps became loose and I wasn't able to tighten them. Had no problems with this set so far, head caps keeping hex shape, wrenches fit tightly. The only regret is that I should've bought it sooner.

This item arrived the next day after delivery with standard shipping, was in mint condition and fit for purpose, and when I contacted support for a quick question I had they responded promptly and were incredibly helpful.Would highly recommend.
