5mm x 12mm 內六角螺絲

Perfect fit for a 3D printer frame repair I was doing—the threads are clean and the hex socket drives without stripping. Nice to have a single replacement instead of buying a bulk pack I’d never use up.

The threads on these little socket head cap screws are perfectly clean and cut cleanly into the metal. Exactly what I needed to fix a loose bracket.

Had to replace a stripped bolt on my mower deck and these fit perfectly. The hex drive bit seated firmly without any wobble, and the black oxide finish seems durable. Glad I could get just what I needed without buying a whole kit.
