M12-1.75 X 50mm 六角承螺絲 | 六角驅動 | 全螺紋 | 8.8 級合金鋼熱黑氧化物 (50 個/包)

Needed a dozen for a jig I was building, and the hex socket drive made tightening them in tight spots much easier than I expected. The fully threaded grip feels solid, and for 50 pieces this pack is a steal.

The black oxide finish on these screws is already proving its worth — no rust after a week in a damp garage. Threads cut smoothly into my steel jig plate, and the hex socket drive makes tightening them a breeze.

Used these for a fixture in my shop press and the black oxide finish looks great with no burrs on the threads. The hex socket drive made installation smooth with a standard Allen key.
