- 304 Marine Grade Stainless: Forged from premium 18-8 (304) Stainless Steel for superior corrosion defense. Essential for docks, coastal decks, and ACQ pressure-treated lumber.
- Extended Structural Strength: The 5/16 diameter delivers professional-grade shear resistance. At 4.5 long, these bolts are Well-suited for through-bolting thick posts and heavy structural timber framing.
