براغي ذات رأس سداسي M16-1.5 × 90 مم | فولاذ عادي فئة 10.9 | ملولبة جزئيًا (25 / عبوة)

Used a few of these on a heavy-duty trailer hitch repair; the 90mm length was perfect for going through the frame and the lock washer. They tightened down smoothly with a socket and show no signs of stripping.

These M16s are solid, hefty bolts for the price—the 10.9 grade means they don't flex when you're torquing them down. The partial threading gave me just the right grip length for a steel bracket assembly.

The partially threaded design made seating them in my equipment frame a breeze, and the hex head grabbed the wrench cleanly without any stripping. Tightened them down to spec and they held firm through a full shift of vibration.
