M6-1 X 80mm 外六角螺絲 | 8.8級鋼本色 | 全螺紋 (800顆/包)

The threading on these screws is clean and consistent through the whole batch, which made assembly on my conveyor line go smoothly. All 800 arrived well-packed and the hex heads gave my socket wrench a solid bite every time.

I needed a full box for a machinery refit, and these fully threaded 80mm screws have held up perfectly so far. The hex head took a socket wrench cleanly without stripping on the first dozen installs.

Used these for a recent conveyor belt repair, and the fully threaded design made alignment a breeze. Each bolt threaded smoothly and held torque perfectly, no stripping even under heavy load. Great value for 800 pieces in a single pack.
