So.... i bought them for a out of the ordinary "project"
i have a Walther G22 in which parts for it just dont exist, and i dont feel like messing with sending it off. so i got some bad ammo which ended up blowing the charging handle off the rifle and ended up not repairable the rifle itself was fine. i bought these along with a set of nuts to go with them and did some rigging to "make" a new charging handle (in which now i have 50 replacements for). so far after around 500 rounds of .22LR ammo the first is still living good. so if these can take the forces of a rifle bolt moving around i'd come to think these would be good in the least for other maybe more relevant uses.

They're bolts
They're still holding the parts I bought them for together.

Good Product
I bought these for use on a 3d printing project. They worked as expected. No issues with stripped threads or bent shafts.

Great
I needed some of these screws for my Prusa mk3s. It was the cheapest option and was overnighted. Highly recommend.

Il princiale vantaggio è che le misure sono molto difficili da reperire in commercio,quindi tutto sommato vale la pena di attendere il tempo di spedizione che, certamente, non è breve. Soddisfatto.
