M27-3 X 100mm 六角頭帽螺絲 | 10.9 級鋼 普通 | 全螺紋 (30 件/包)

The fully threaded length made aligning the flange a lot easier than digging through mixed boxes. Class 10.9 steel feels reassuringly solid when I torque them down, and the hex heads seated cleanly in my socket. No stripped threads across all thirty pieces, which is what I care about most.

These bolts handled the heavy load on my press brake fixture perfectly — the 10.9 steel didn't flex at all. The 100mm length gave just enough thread engagement for the application.

Pulled these out of the package and they threaded perfectly into my press jig with zero binding or galling, and the hex heads gave my socket a solid, confident grip. It's nice when a bolt this heavy-duty feels precise instead of sloppy.
