M16-1.5 x 50mm 外六角螺絲 | 等級10.9 鋼鍍鋅 | 全螺紋 (25個/包)

Zinc plating looks clean and even on all 25 bolts, and the full threading made it easy to cut custom lengths for my jig setup. No stripped heads or burrs after driving a dozen into steel, which is exactly what I needed for a load-bearing frame.

The zinc plating on these bolts held up well during assembly, no rust or damage after tightening with a socket. They seated cleanly into the M16 holes and the hex head gripped perfectly. Exactly what I needed for a machinery frame job.

Thread engagement was perfect on these M16 bolts—the 50mm length and fully threaded design made mounting my new motor bracket a breeze. The Class 10.9 steel feels solid and the zinc coating looks like it'll hold up well.
