M12 X 25mm 內六角螺絲 | 低頭六角驅動 | 8.8級合金鋼 (50 / 包)

Class 8.8 alloy steel means these M12s won't strip or warp under heavy clamping. The low head profile was perfect for a tight jig clearance I was fighting with, and all 50 came with cleanly cut threads.

The low head profile cleared my jig’s tight access point where a standard cap screw would’ve been a pain to reach. Threads chased cleanly into the tapped holes with no binding, and all 50 pieces had a consistent, even coating. These will definitely go back in my tooling drawer for the next build.

Installed them on a milling fixture today and the hex socket drive let me torque them down precisely without stripping. The Class 8.8 alloy steel feels solid enough for repeated use in tooling setups.
