6334 Carbon Steel Long Hex Coupling Nuts Galvanized With Nickel Plated

6334 Carbon Steel Long Hex Coupling Nuts Galvanized With Nickel Plated

Product Overview

Our 6334 Carbon Steel Long Hex Coupling Nuts are engineered to deliver unmatched strength and corrosion resistance for demanding industrial applications. Featuring a dual-layer protective coating (hot-dip galvanized + nickel-plated), these nuts combine the rugged durability of carbon steel with enhanced environmental protection. Designed to join threaded rods, bolts, or studs securely, they are ideal for structural, marine, and heavy machinery projects requiring long-term reliability.

Key Features

✅ Dual-Layer Corrosion Defense

  • Hot-Dip Galvanized (HDG) Base: Zinc coating (≥85µm, ASTM A153) provides sacrificial protection against rust and oxidation.
  • Nickel-Plated Finish: Outer layer (5–10µm, ASTM B733) adds aesthetic appeal, abrasion resistance, and extra defense in harsh environments.

✅ High-Strength Carbon Steel

  • Grade 6334 Carbon Steel: High tensile strength (up to 1,000 MPa) for heavy-load applications.
  • Heat-Treated Durability: Resists deformation under extreme torque or vibration.

✅ Long Hex Design

  • Extended Thread Engagement: Greater length ensures secure connections for threaded rods or stacked bolts.
  • Hexagonal Shape: Compatible with standard wrenches (6mm–24mm) for easy installation.

✅ Certified Quality

  • Compliant with ASTM A563 (carbon steel nuts) and ISO 4032 (metric hex nuts).
  • RoHS and REACH compliant for global environmental safety.
