براغي رأس سداسي 7/8-14 × 9" | صناعة أمريكية | سبيكة فولاذ درجة L9 مطلي بالزنك الأصفر | ملولبة جزئيًا (15 / عبوة)

Threaded them into a hydraulic press frame and the L9 alloy steel held up perfectly under torque. The yellow zinc coating on these 7/8-14 hex heads looks tough and hasn't shown any rust yet.

I needed a heavy-duty fastener for a press rebuild and these hex heads let me torque them properly without slipping. The yellow zinc coating looks solid and should hold up in a shop environment.

Needed a heavy-duty bolt for a press frame repair, and these held up great under the torque. The partial threading made alignment much easier than a fully threaded bolt would have. Only nitpick is that the yellow zinc coating feels a bit thin in a couple spots.
