M3-0.5 X 20mm Zeskantbout | Klasse 8.8 Staal Onbehandeld | Volledige draad (20000/stuk)

The heads are crisp and grab a socket perfectly, making assembly on our production line noticeably faster. For nearly 20,000 pieces, the threading is impressively consistent with no burrs or duds in the batch. It's a solid value for high-volume industrial work.

Ordered these for a production run and the fully threaded design saved me from having to stock multiple lengths. The hex heads seat cleanly with a standard Allen key, no stripped corners. Twenty thousand in one box is a lot of hardware, but they came well packed and sorted.

I needed a massive quantity of M3 bolts for a production run, and these hex head cap screws fit the bill perfectly. The class 8.8 steel feels plenty strong for our assembly jigs, though a few heads showed slight burrs. For the price per piece at this volume, it's a solid deal.
