Types of Metric Weld Nuts

Metric Hex Weld Nuts

Metric hex weld nuts are internally threaded fasteners designed to be welded directly onto sheet metal or structural components. Available in both short and long pilot styles, they provide flexibility for use in thin or thick materials. The pilot design ensures accurate alignment and strong thread engagement, while the projection weld points allow for excellent current conduction and secure bonding. These fasteners are commonly used in automotive, HVAC, and chassis manufacturing where durable, welded threads are required.

Metric Square Weld Nuts

Metric square weld nuts feature a four-sided profile that helps prevent rotation during installation, maintaining stability throughout the welding process. They are offered in styles such as four projection, round projection, and flat seat, each tailored to balance current flow, strengthen localized weld points, or distribute load evenly. Square weld nuts are relied upon in automotive frames, fabricated structures, and industrial assemblies where strong, permanent threads are essential.

Metric Weld Nuts - Industry Applications

Metric weld nuts are widely used in industries that require permanent threaded connections without relying on through-bolts or loose nuts. Automotive manufacturers use them for chassis, body, and frame assemblies, while HVAC companies rely on them to secure panels, ducts, and enclosures. Fabricators and equipment builders depend on weld nuts to create durable, reusable threads in sheet metal where speed and accuracy are vital.

The advantage of weld nuts is their ability to integrate into production lines seamlessly. They simplify assembly, reduce part counts, and improve consistency in high-volume manufacturing. By providing stable, permanent threads, metric weld fasteners save time while ensuring long-term structural integrity.

Metric Weld Nuts - Material Options

South Coast Fasteners stocks metric weld nuts in materials chosen for strength and weldability.

Steel

Steel is the standard material used for weld nuts due to its toughness, durability, and ease of welding. It performs reliably under the heat and pressure of welding, providing secure and lasting connections. Steel weld nuts are trusted in high-production environments such as automotive plants and fabrication shops where consistent performance is critical.

Metric Weld Nuts - Available Finishes

South Coast Fasteners offers metric weld fasteners in finishes designed to align with production requirements.

Plain

Plain steel weld nuts are supplied without additional coatings, making them cost-effective for manufacturing processes where coatings are unnecessary. They are also commonly used in projects where weld nuts will be painted, plated, or otherwise treated after installation. By maintaining weld integrity and keeping costs low, plain finish weld nuts remain a popular choice in production environments.
