براغي رأس سداسية مقاس 1"-8 × 6" | فولاذ درجة 5 زنك أصفر | خيط جزئي (25 / عبوة)

The threads on these matched up perfectly for the industrial press I'm rebuilding, and the yellow zinc finish looks clean and rust-resistant right out of the box. The partial threading gave me just enough grip length without bottoming out. Solid buy for the price.

Used these to mount a heavy gearbox to a steel frame and the Grade 5 strength held up perfectly under load. The partial threading made aligning the first few threads much easier than a fully threaded bolt would have.

These bolts cinched down perfectly on my press jig with a standard socket—the Grade 5 steel feels solid and the yellow zinc coating is a nice touch for rust resistance.
