M16-1.5 X 45mm 六角頭螺絲 | 10.9級鋼原色 | 全牙 (25/包)

I was worried about getting the right fit for a heavy-duty bracket, but these M16 bolts threaded perfectly into the pre-tapped holes. The hex head made it easy to drive with a socket, and the 10.9 steel feels very solid under load. Overall, exactly what I needed for the job.

Torqued these down to spec on a pump mount assembly and the hex heads held perfectly without any rounding. The 10.9 grade steel gives me real confidence in the joint integrity. Exactly what I needed for heavy-duty equipment repair.

Threads cut perfectly clean on my lathe, and the 45mm length seated flush where I needed it. The 10.9 hardness took a torque wrench without a hint of stripping, which is exactly what I hoped for on this assembly.
