Customer Reviews (4.6 / 5 · 5 reviews)

Amelia Y. ★★★★★

The hex heads on these bolts give my socket wrench a clean grip, making assembly on my press fixture a breeze. The yellow zinc finish on each piece looks uniform and should hold up fine in my shop.

Richard ★★★★★

Was tightening up a piece of shop equipment and these hex heads grabbed the socket perfectly with no slipping. The fully threaded shank let me snug them down into a tapped hole without any extra spacing.

Miles G. ★★★★★

The yellow zinc finish on these L9 screws looks evenly applied, and they threaded into my fixture without any binding. For a 200-count box this price feels fair, especially since every single one came out of the package clean and ready to use.
