M30-3.5 x 150mm 六角頭螺絲 | 10.9 級鋼原色 | 全螺紋 (20 入/包)

Finally found some heavy-duty M30s that don't strip under torque—used them to secure a press frame and the hex head gave my socket a solid grip. The fully threaded length made it easy to cinch down through thick flanges without any wobble.

These bolts drove in smooth with a standard socket and the Class 10.9 rating gives me confidence they'll handle the heavy load I'm putting on them. All twenty were fully threaded and clean, no burs.

Thread engagement is perfect on these bolts—the fully threaded shaft let me get the exact depth I needed on a heavy press frame. They torqued down smoothly without any galling.
