3/4-10 X 7" 六角ボルト | グレード5鋼イエロージンク | 半ねじ (35個/パック)

I’m six feet up on a scaffold and the hex head grabbed my 15/16 socket without slipping once. The partial threads on these 7-inchers bit into the steel beam just right, and the yellow zinc finish hasn’t shown a speck of rust after a week of rain. Grabbed a second box already.

The yellow zinc coating on these has held up nicely against oil and grime in my shop, and the hex heads grab a socket cleanly every time. I needed a 7-inch partial thread for a jig build and these fit the bill without any hunting.

The partial threading is exactly what I needed for a heavy jig—the grip section bites cleanly while the threads engage fully. Yellow zinc finish looks solid and hasn't chipped after a week of wrenching.
