براغي رأس سداسي مقاس 1/2-13 × 5 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئياً (120 / عبوة)

I needed heavy-duty bolts for a press frame, and these Grade 8 screws handled the torque without stripping. The hex heads fit my socket perfectly, and the zinc plating looks like it'll resist rust well.

The threading is clean and the zinc coating looks even across all 120 pieces, which made sorting them for my jig build a breeze. These grade 8 bolts torqued down without any stripping, and the partial threads gave me just the right grip for a tight assembly.

Picked up a box for building a press frame, and the zinc plating on these Grade 8 bolts is flawlessly smooth—no burs or rough edges to snag gloves. Each head grabbed perfectly with a 3/4" socket, and the partial threading made cinching down heavy brackets a breeze.
