1-1/4-12 x 3" 六角頭螺絲 | 美國製造 | 8級鋼 黃鋅 (25 / 包)

Bolts came in one tidy package with zero nicks on the yellow zinc finish, and the hex heads are crisp enough for a 12-point socket to grab without slipping. Went through a whole machine frame build without a single one binding up, which is rare for grade 8 in my experience. Exactly what you want whe

The threading on these is perfectly clean, so they drove in without any binding or resistance. I used them on a trailer hitch mount and they’ve held tight through rough roads. Solid buy.

These are the first hex bolts I've bought that actually warrant the grade 8 stamping. The yellow zinc finish is even and consistent across all 25 pieces, and they torqued down cleanly without a single stripped thread.
