HNB's ASTM A307 Grade A Hot Dip Galvanized Hex Bolts are one of the most common types of general purpose steel bolts, especially for wood construction and certain structural connections.
Common Applications:
Hot Dip Galvanized (HDG) Bolts feature a thick zinc coating applied by immersing fasteners in molten zinc (~450°C / 840°F), producing a durable, more corrosion resistant surface compared to Zinc Electro Plated Fasteners.
FastPro Tip: Pair with HDG Nuts, which are tapped oversized to accommodate the zinc coating and ensure proper fit with Hot Dip Galvanized Bolts, Rods and Anchors. Click on any product for more detailed information...
