1/2 Grade 2 HDG Hex Nut

Description

1/2 Grade 2 Hot-Dipped Galvanized (HDG) Hex Nut is a heavy-duty fastener that offers superior corrosion resistance over zinc alternatives, often used for exterior, structural, and high-moisture fastening applications.

Hex nuts have a flat bearing surface, a six-sided body, and a fully threaded interior designed to fasten onto a compatible bolt or threaded rod to secure components together. Their six-sided body allows for easy tightening with standard wrenches and sockets, and the hot-dipped galvanized coating provides reliable performance in demanding outdoor and moisture-heavy environments.

Grade 2 Hot-Dipped Galvanized (HDG)

• Grade 2 HDG hex nuts have a higher corrosion resistance than zinc alternatives due to their thick, hot-applied zinc coating
• These are well suited for exterior construction, high-moisture environments, and structural applications where long-term durability is required

1/2 Grade 2 HDG Hex Nut Features

• High torque capacity due to the six-sided body, allowing use with wrenches, ratchets, and impact drivers
• Fully threaded interior designed to engage completely with the mating bolt or threaded rod for a secure, reliable connection
• Heavy-duty corrosion resistance from the thick HDG coating, suitable for exterior and moisture-exposed structural assemblies

Common Uses

• Exterior structural assemblies, construction framing, and outdoor equipment installations
• High-moisture environments including boardwalks, piers, bridges, and coastal structures
• Applications requiring long-term durability and corrosion protection in demanding outdoor conditions

Application

• Thread onto a compatible bolt or threaded rod by hand until snug against the mating surface, then tighten with a wrench or socket sized to the hex body
• Use with a washer between the nut and mating surface to distribute load and prevent surface damage where required
• Ensure the mating bolt or threaded rod shares the same thread diameter, pitch, and grade before assembly

Tips

• Always verify that the bolt or threaded rod shares the same thread diameter and pitch as the hex nut before assembly
• Hex nuts are measured by their thread diameter and pitch, matching the bolt or threaded rod they are paired with
• Use HDG washers and fasteners throughout the assembly to maintain consistent corrosion protection and avoid galvanic corrosion
