7/16-20 X 7-1/2" 六角頭キャップスクリュー | アメリカ製 | グレード8スチール イエロー亜鉛メッキ（110個/パック）

I needed a full box of these for a heavy equipment repair, and the 7/16-20 threads engaged perfectly with the Grade 8 strength I was counting on. The hex heads let me torque them down with a socket without any stripping, and they came packaged securely.

Pulling these out of the package, the hex heads have a precise bite for my socket wrench, and the yellow zinc finish looks like it'll resist corrosion well. For a 7/16-20 x 7-1/2" bolt, the Grade 8 steel feels seriously strong, and the 110 count means I've got plenty for this job and spares.

Finally a fastener that’s actually beefy enough for heavy equipment—the hex head on these gives solid wrench bite even after multiple tightenings. The yellow zinc finish looks clean and seems to resist rust so far on the farm rig I used them on.
