Avery ★★★★★

Bought these for a heavy-duty jig I'm building, and the fully threaded design made installation a breeze. The Grade 8 steel feels solid and the yellow zinc coating looks like it will hold up well in the shop. This bulk pack should last me a while.

Daniel U. ★★★★★

I needed fully threaded fasteners for a heavy equipment repair and these grade 8 hex bolts torqued down perfectly without any stripping. The threads were clean and the yellow zinc coating has held up well so far.

George H. ★★★★★

The yellow zinc coating on these grade 8 bolts looks uniform and tough, and the fully threaded body made them perfect for a tight machinery repair. The 675-count box is a solid deal for the price.
