M12-1.25 × 45mm 六角頭帽螺絲 | 10.9級鋼 普通 | 全螺紋 (325 / 包)

Pulled these out of the box and the threads are perfectly clean, no burs or gunk. The 10.9 grade gives me confidence torquing them down in my press jig without worrying about snapping.

I needed fully threaded bolts for a heavy-duty bracket install, and these 45mm lengths gave me just the right bite without bottoming out. The Class 10.9 steel feels solid and the threads were clean, no burs.

The hex head seated perfectly in my socket without any slippage while torquing down some heavy equipment brackets. These 45mm lengths are exactly what I needed for bolting thick steel plates together.
