براغي رأس سداسية مقاس 1"-8 × 5-1/2" | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (10 / عبوة)

The partial threading on these Grade 5 bolts made aligning the heavy machinery frame much easier than with fully threaded ones. The yellow zinc coating looks tough and hasn't shown any rust after a week in a damp shop.

Bought these to replace some worn bolts on a press we have at the shop. Threads are clean and the zinc coating looks like it’ll hold up well. Fit right into our existing equipment without any fuss.

Needed some seriously strong bolts for a press build, and these grade 5 hex heads drove in perfectly with a socket—no stripping at all. The yellow zinc finish looks clean and should hold up well in a shop environment.
