براغي رأس سداسية M4-0.7 × 10 مم | فولاذ درجة 8.8 مطلي بالزنك | سنون كاملة (800 / عبوة)

Thread count was exactly right for the job I had on an assembly line, and the zinc plating seems decently thick so far. These M4s feel sturdy enough for repeated tightening without stripping.

Used a handful of these to replace stripped screws on a small CNC machine, and the hex head fit the socket driver perfectly without any wobble. The 800-count bag is more than I’ll ever need, but the price per screw was too good to pass up.

The zinc plating on these M4 bolts gave them a nice, uniform finish, and they seated cleanly into my aluminum bracket with no binding. For 800 pieces, the price is hard to beat when you're doing a big assembly run.
