25Pcs M8 Hex Bolts M8x20mm Hex Head Bolt 304 Stainless Steel

I used this M10 bolt and nut set as the “core” for a 3D-printed attachment that chucks into a power drill, and it worked really well for that kind of project. The bolts are straight, threads are clean, and the 60mm length is a nice sweet spot — long enough to pass through a printed part, washers, and nut with room to spare, without feeling absurdly oversized. The 304 stainless feels solid and inspires confidence when you’re spinning it with a drill; no sketchy flex or mystery-metal vibes. The included flat and spring washers are a nice bonus. Having everything in one kit made it easier to design the print around the actual stack height (bolt head + washer + part + washer + nut). For 3D printing specifically, the tolerances were consistent enough that I could model the holes for an M10 clearance fit and have everything line up without needing to ream or force it. Only downsides: the nuts are a bit chunky, so if you’re designing a compact part or recessing them into the print, you’ll want to account for their height and outer diameter. The washers are also pretty standard thickness — fine for most uses, but if you want a really wide load spread on plastic, you might end up upgrading to larger washers later. Overall, though, for a simple, sturdy, metric hardware set to pair with a 3D-printed drill attachment, this did exactly what I needed and made the mechanical side of the project pretty painless

Perfect

The set of bolts are decent products. It had a good sturdy thread and quality. It is handy to have its in the tool box. I used its to fix things around the house. It served its purpose . Good Value for the price. Recommend it ! Great Shipping! Thanks !

Good quality stainless steel! I need something that would not rust so a tried getting several of these to rust with some weak acids, salt water, scratched then up real good and left them in the whenever for over a month and they passed ask my tests. They're strong too. I would buy again

Product correct with fast shipping at a fair price /

Decent hardware as far as I can tell. Clean cut, nice threads, etc. It'll be used indoors in a controlled environment, so they should do very well.

They're bolts... they bolt things... so 2 thumbs up, lol

Nice and sturdy.
