About this item
- Top-Notch Components: Comes with Grade 307A carriage bolts, Grade 2 hex nuts, and USS flat washers for solid performance.Hot dip galvanized coating for superior corrosion resistance.
- Perfect for Heavy Projects: Flat head gives a semi-flush look, ideal for decks, gazebos, pergolas, and other tough jobs.
- Easy to Install: Full thread from neck to tip means better nut grip and strength. Square neck holds tight in wood, stopping the bolt from spinning when tightening. This makes a secure, vibration-free connection, saving you time.

- Various Sizes Available: These carriage bolts come in many sizes, suitable for heavy tasks. Different sizes meet different needs, offering strong support for all kinds of projects.
