براغي رأس سداسية مقاس 5/8-18 × 4" | صناعة أمريكية | فولاذ سبيكة PFC9 مطلي بالزنك الأصفر (25/عبوة)

The yellow zinc finish on these bolts held up well against a bit of moisture in my shop, and the hex head gave my socket wrench a solid grip while I tightened them down on a jig fixture.

These bolts torqued down perfectly on my skid steer attachment without any thread binding. The yellow zinc coating on the PFC9 alloy steel gives them a nice consistent finish for heavy use.

Installed these on a heavy-duty press attachment I've been working on, and the hex heads make torquing them down a breeze. The yellow zinc coating looks solid and should hold up fine in my shop environment.
