M20-2.5 x 120mm 六角頭螺絲 | 10.9 級鋼 無處理 | 半牙 (10 顆/包)

The partially threaded design made alignment way easier when I was bolting down a metal baseplate. These 10.9 grade screws feel rock solid, definitely can handle the torque my impact driver puts out.

Needed a beefier bolt for a heavy jig I'm building, and these class 10.9 screws handled the torque without a hint of flex. The hex head seated perfectly in my socket, and the partial threading made aligning the load-bearing section straightforward.

The partially threaded design made alignment a lot easier when I was torquing these into a flange, and the hex head sat perfectly in my socket without slipping. Class 10.9 steel feels plenty rigid for the job, so I’m glad I grabbed a pack of ten.
