براغي رأس سداسي M30-3.5 × 190 مم | فولاذ فئة 10.9 عادي | خيط جزئي (2 / عبوة)

The partially threaded design made seating them in our press frame a lot easier than fighting full-length threads. Machined threads are clean, and the hex heads took a socket without any slop. Two solid pieces for the price.

Bought these for a large jig build and the thread engagement felt rock-solid from the first turn, glad I went with the partially threaded version for clamping force. The Class 10.9 steel took the torque without any flex.

Used these for a heavy-duty press frame rebuild and the partial threading made alignment much easier before torquing down. The 10.9 steel feels solid, no flex at all.
