High quality well packaged and comprehensive set of stainless hex head cap screws
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.

15000 pcs - They were not kidding - I have enough Screws, Nuts and washers for a lifetime. This set is perfect for small projects, 3D printer maintenance, and furniture repairs. The screws and nuts are solid and well-machined, with consistent threads and a durable black finish. I like that it includes a wide range of sizes (M2 to M6) and five matching Allen wrenches. Everything came neatly organized in a compartmentalized case, which makes it easy to find what I need quickly. Great value for anyone who regularly works with metric hardware.

Ottimo prodotto. La parte negativa è: sembrano tanti ma per ogni tipo di vite il numero è esiguo.
