براغي رأس سداسي M12-1.75 × 40 مم | فولاذ فئة 10.9 مطلي بالزنك | ملولبة بالكامل (100 / عبوة)

Used them to bolt down a heavy steel workbench frame and every single one of the 100 threaded in clean without a single stripped thread. The Class 10.9 strength gives me real peace of mind for the load, and the hex heads grab a socket perfectly every time.

The zinc plating on these is really uniform and the threads are perfectly clean, so they seat without any fighting. Used a full hundred on a steel frame job and had zero stripped heads or rounded hexes.

Grabbed a pack for the equipment assembly we’ve been doing, and the threads are completely clean—no binding when I ran them in with a socket. The hex heads grip tight without rounding, and the zinc plating has held up against some light moisture so far.
