براغي سداسية الرأس 1"-8 × 4" | صناعة أمريكية | سبائك فولاذية L9 بطلاء زنك أصفر | ملولبة جزئيًا (10 / عبوة)

Pulled an old truck axle apart for a custom trailer build, and these L9 bolts held up perfectly under the torque. The zinc coating seems heavier than standard hardware store stuff, which is a nice bonus. Not a single issue threading into the tapped hole.

Used these on a milling machine frame rebuild, and the partially threaded design made alignment far easier. The yellow zinc coating seems tough enough to resist shop grime. Really solid fasteners for the price.

Got these for heavy equipment repairs and the yellow zinc coating has held up well against dirt and moisture. The hex head gave my socket wrench a solid grip for torquing down to spec.
