5/8-11 × 10" براغي رأس سداسي | صنع في الولايات المتحدة | سبيكة فولاذ درجة L9 زنك أصفر | خيط جزئي (25/عبوة)

The yellow zinc finish on these Grade L9 bolts is holding up great in the shop, no rust after a few weeks of exposure to cutting oil. Partial threading made alignment a lot easier when I was bolting down my press base. Fit my 5/8 socket perfectly right out of the box.

Pulled the old ones off my planer and these threaded in smooth like butter. The L9 alloy steel feels way tougher than the hardware store stuff.

Used a couple of these to bolt down a heavy motor mount, and the hex heads grabbed my socket perfectly without stripping. The yellow zinc finish looks solid and the partial threading gave me just the right grip for a snug fit against the frame. For 25 pieces at this grade, that’s a solid value.
