براغي رأس سداسي M24-3 × 380 مم | فولاذ كلاس 10.9 عادي | جزئي الخيط (1/عبوة)

Honest truth: I was nervous about seating a 380mm bolt without cross-threading, but the partial thread caught clean and the hex head took my breaker bar without a hint of stripping. Solid piece of steel for the price.

Used this to secure a jig on a milling machine and the 10.9 steel held torque perfectly without stripping. The length is just right for thick flanges, though you'll need a hefty wrench. Glad I went for the grade—no wobble at all.

I needed a heavy-duty bolt for a press frame repair, and the 380mm length fit perfectly through the assembly. The partially threaded design gave good grip while leaving room for a lock washer under the hex head. No issues torquing it to spec with a socket.
