I picked up this 440-piece M3 nuts and bolts set, and it’s been a fantastic addition to my workspace. The variety of lengths included makes it super versatile for all kinds of projects, from 3D printer upgrades to electronics and general DIY repairs. The quality is excellent—the bolts and nuts are well-machined with clean threads, making assembly smooth with no stripping or misalignment issues. The stainless steel construction ensures durability and rust resistance, so I don’t have to worry about long-term reliability. I also appreciate the organized storage case—everything is neatly sorted, making it easy to find the right size without rummaging through a messy pile of hardware. The assortment is well-balanced, with plenty of each size to cover most needs.

I was a bit concerned at the reviews for this item and didn't really know what to expect would arrive! Shouldn't have worried though. Packaging was fine, box taped shut and a little bit of packing inside the case kept all the components in their respective compartments 100% even the washers. Case really lovely for organisation, lid label tells you which compartment to head for to get the bit you want. Allen key and tweezers included, that's a nice touch. I didn't count them, hahaha, over a thousand bits in there, if there's a couple missing I don't care, there might even be more than I bought :o) The threads all look perfect, and the first two I used fitted the heat inserts I bought absolutely perfectly so I'm very happy. Box label says 304 Stainless Steel which is bog standard SS, it won't stand up to chemical attack like 316 will with Molybdenum in it, and 304 can be pitted by continual attack from salt water, but for general use and rainwater/tapwater etc these are what you want. Huge range of sizes, lots of each, washers and nuts, and a storage case all for a tenner-ish. Brilliant :o)

This M2.5 screw set has a massive selection of hex and pan head screws, perfect for electronics or small projects. The screws feel well-made and come neatly organized. Only wish there were a few more lengths included, but overall excellent value.

Good set of nuts and bolts. I like the inclusion of Allen keys. Only criticism is that this kit really needs washers. I had to buy these separately. To be fair though they sent me what was advertised, so maybe I shouldn't complain.

Bought to use in 3d printing projects. Nice strong bolts that hold well. Lots of different sizes. Perfect and all within an easy to use box

Exactly what I was looking for.

Very useful to have on hand, they are high quality screws of decent stainless steel, they start easily with a very clean thread. My only small gripe is that they could do with more of the smaller lengths in the box or have a ratio that leans more to the shorter ones as I always end up running out of those first, that could just be me though lol.

Great selection with nuts and washers. Good value.
