M6-1 x 90mm 六角頭螺絲 | 10.9級鋼 無處理 | 部分螺紋 (900顆/包)

The hex head design works perfectly with my socket set, saving time on assembly. These 90mm screws hold firmly without any wobble, even under decent torque. Exactly what my industrial project needed.

I needed partially threaded M6 bolts for a jig that needed a smooth shank, and these 90mm ones fit the bill perfectly. The 10.9 grade steel feels solid, and the hex head drives cleanly with a socket.

Got these to replace bolts on a heavy duty press jig at work — the class 10.9 rating holds up well under torque. Full 900 count in one box saved me a trip to the hardware store mid-project.
