M12 x 30mm 內六角螺絲 | 低頭六角驅動 | 8.8級合金鋼 (50個/包)

Used these to rebuild a couple of jigs in my shop, and the 8.8 alloy steel took the torque without any stripping. The low head profile is a nice touch for tight clearances, and all 50 came with clean threads.

The hex socket drive seated perfectly on my driver without any wobble, and all 50 pieces had clean threads with no burrs. I used them to bolt down a steel jig plate and the Class 8.8 alloy held up great under repeated torque. Fast shipping too, which never hurts.

The low head profile saved me from having to modify my tooling mount to clear a tight guard. Threads were clean and the hex drive seated perfectly without any wobble on my driver.
