M16-2 X 20mm 六角頭螺絲 | 10.9 級鋼素色 | 全螺紋 (每包 50 個)

Had to replace some original bolts on a piece of heavy equipment and these M16-2 x 20mm cap screws fit perfectly. The Class 10.9 steel is definitely tough and the fully threaded design gave me plenty of grip.

Pulling these fully threaded M16 screws out of the pack, I could feel the quality of the Class 10.9 steel right away. They tightened cleanly with a socket drive on my equipment frame, no stripping or binding at all. For a 50-piece pack at this grade, the price feels more than fair.

The hex head on these cap screws grabs my socket wrench perfectly, and the 20mm length is exactly what I needed for a tight assembly point. With 50 in the pack, I have plenty spares for future repairs without overordering.
