Review: Great Quality and Value – Perfect for DIY and 3D Printing! - 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. If you’re looking for a high-quality, well-organized M3 hardware kit for 3D printing, PC builds, or general projects, this set is a must-have. Great value for the price!
Review: Faultless - 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)
