براغي رأس سداسي 3/8-16 × 2-1/2 بوصة | صناعة أمريكية | سبائك فولاذ درجة L9 بزنك أصفر | خيط جزئي (50 / عبوة)

Put these on a heavy-duty equipment mount and the Grade L9 strength gave me peace of mind that they wouldn't snap. The yellow zinc coating looks good and the partial threads made alignment a breeze.

Used these on a jig fixture I’m building, and the partial threads make all the difference for pulling plates tight without bottoming out. Grade L9 feels seriously stout in the hand, and the hex heads barely rounded under a strong socket wrench.

The yellow zinc finish has held up nicely after a few weeks in a slightly damp shop, and the partial threads grab really well in my fixture plates. The L9 alloy steel feels dense and solid when you torque it down with a socket, so I’m glad I went with these over cheaper hardware.
