3/4-16 × 2" 六角頭螺絲 | 美國製造 | L9合金鋼黃鋅 | 全螺紋（20個/包）

I've been using these for heavy equipment repairs and the hex head gives solid bite with a socket wrench, no stripping issues so far. The fully threaded design grabbed perfectly in a tight spot where I needed extra grip.

Yellow zinc finish held up fine through a couple of oily shop jobs, and the fully threaded grip gave me zero slip when torquing down a fixture plate. For the price on a twenty-pack of L9 alloy, these are stout enough that I’m already planning to order another set.

The threads on these L9 bolts are perfectly clean and uniform, so they threaded in smoothly without any binding. I used them to re-secure a heavy press base, and the yellow zinc finish gives me confidence they'll resist corrosion over time. This pack of twenty was exactly what I needed for the job.
