براغي رأس سداسي M48-5 × 160 مم | فئة 10.9، فولاذ عادي | جزئي الخيط (5/عبوة)

The partial threads made alignment on my equipment frame much easier than full-threaded bolts, and the 10.9 steel feels rock-solid under torque. Wrench fit on the hex head was snug from the first turn, no stripping.

The hex head grabbed my socket wrench without slipping, and the partially threaded shaft made alignment on the flange a breeze. These M48x160s are beefy enough for the press frame I’m building.

These fit perfectly on a heavy-duty conveyor support I've been rebuilding; the 10.9 grade steel holds torque without stripping like the cheaper bolts I used before. Only real complaint is the 160mm length made threading them into tight spots a bit of a chore, but a socket extension sorted that out.
