براغي رأس سداسي M16-2 × 90 مم | فولاذ عادي فئة 10.9 | ملولبة جزئيًا (20 / عبوة)

Installed these on a heavy conveyor frame I’m rebuilding, and the partial threading made alignment much easier than with fully threaded bolts. The hex heads seated firmly with a standard socket, and all twenty pieces came clean and burr-free. Solid fasteners for the price.

These threaded right up into my milling machine's t-slots without any binding, which was a relief. The partial threading gives just enough grip without needing the full length to be threaded. Solid 10.9 strength for the price.

I needed a strong bolt for a heavy-duty repair and the partially threaded design held the load perfectly without slipping.
