Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

National Hardware 3.5 in. L Black Steel Extra Heavy Auto-Close Gate Hinge Set is built for gates that demand enduring strength and dependable, hands-off closing. With a robust 3.5-inch length and solid steel construction, this hinge set is designed to stand up to frequent use, helping your gate stay aligned and secure year after year.

Key features that set this hinge apart:

  • 3.5 inch length provides sturdy mounting and reliable support for heavier gates.
  • Extra heavy steel construction delivers superior durability for gates that see daily opening and closing.
  • Black finish offers a low-profile look that blends with most gate styles while reducing visible wear over time.
  • Auto-close action built into the hinge helps your gate close automatically, improving security and convenience without manual effort.
  • Single-set packaging (carded) simplifies replacement when you’re refreshing or upgrading gate hardware.
  • National Hardware brand reliability, designed to fit common gate hardware standards and typical residential applications.

Use cases and ideal applications

This extra-heavy auto-close hinge is a strong match for residential or rural gates that experience frequent use. It’s well-suited for wooden gates, metal gates, or mixed-material installations where a sturdy hinge with reliable self-closing action is desired. Perfect for property boundaries, garden entrances, and any gate that benefits from a controlled, automatic close for safety and security.

Practical installation considerations

  • Ensure the hinge length (3.5 inches) aligns with your gate frame and post dimensions for proper mounting.
  • Use the fasteners appropriate for your mounting surface and material to maximize longevity and performance.
  • After installation, test the self-close action and adjust alignment to achieve a smooth, controlled close every time.

Upgrade your gate hardware with this purpose-built, heavy-duty auto-close hinge set from National Hardware. It combines a compact 3.5-inch profile, durable black steel, and a reliable self-closing mechanism to deliver secure, hands-free operation for gates that see real-world use.
