Customer Reviews (4.4 / 5 · 5 reviews)

Jacob I. ★★★★★

These bolts fit perfectly into my pre-drilled holes, the square neck seated itself firmly with no spinning. The zinc coating looks clean and uniform, and having 300 in a pack means I won't run out mid-project. Exactly what I needed for assembling a heavy-duty workbench frame.

Harper ★★★★★

The square neck grabbed the wood instantly on my fence repair, no spinning at all even with a wrench. Zinc coating looks clean and the full threading made it easy to add a washer and nut.

Edward I. ★★★★☆

The square neck grabbed nicely into the wood as I tightened them, no spinning at all. Zinc coating looks clean and uniform across all 300 pieces. Only wish the threads were a hair cleaner right out of the box.
