M12-1.5 X 100mm 六角頭螺絲 | 10.9 級鋼 無鍍層 | 全螺紋 (200 / 包)

Bought these for a machine rebuild and the fully threaded length made alignment way easier than fumbling with partial threads. The 10.9 hardness shows in how cleanly they torqued down without any stretch. Bag count was exactly 200, no surprises.

The hex head sits perfectly in a socket wrench, no wobble or stripping even under heavy torque. For a 100mm fully threaded M12 in class 10.9, the finish is surprisingly uniform. Bought a full box for our assembly line and haven’t had a single dud yet.

The threads are clean and consistent across all 200 pieces, which made setting up my jig way faster than expected with the 10.9 hardness holding torque nicely. Only downside is the plain finish needs a bit of oil if you're leaving them exposed outdoors, but that's on me.
