Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The zinc plating looks clean and corrosion-resistant, exactly what I needed for a small structural repair. These 1/4-20 carriage bolts fit the machine frame perfectly, and having 300 in a pack means I've got spares for future projects.

Andrew M. ★★★★★

Perfect fit for fastening my workbench legs—the square necks seated nicely into the wood without spinning. Zinc plating looks clean and sturdy, and having 300 in one pack means I won’t run out mid-project.

Leo I. ★★★★★

The square necks on these 1/4-20 carriage bolts seat perfectly into pre-drilled holes—no spinning, which saves a ton of frustration. I’ve gone through half the box for a steel frame project and the zinc plating has held up nicely so far.
