Our GB13680 M4 Square Weld Nut is a high-quality, reliable fastening component designed for permanent and secure attachment to sheet metal or other materials through welding. Manufactured in strict accordance with the Chinese GB13680 standard, this nut ensures consistent dimensions, reliable performance, and excellent compatibility.

The square shape provides superior stability, preventing rotation during the assembly process and offering a larger surface area for welding. This makes installation easier and ensures a stronger, more durable weld joint. The M4 metric coarse thread is precision-cut to provide smooth engagement with compatible M4 bolts and screws, guaranteeing a secure and tight fit.

These weld nuts are ideal for use in applications where a strong, fixed threaded point is required on the opposite side of a panel, especially in blind or hard-to-reach areas.

 

Key Features & Benefits:

Compliant with GB13680 Standard: Assures quality, consistency, and dimensional accuracy.

M4 Metric Thread: Standard thread size for versatile use with M4 fasteners.

Square Design: Provides anti-rotation特性 (anti-rotation特性 - characteristic) and increased weld surface area for a stronger bond.

Secure Welding: Facilitates permanent attachment to metal surfaces through projection welding or other suitable welding methods.

High-Strength Carbon Steel: Offers excellent durability and reliable load-bearing capacity. (Note: Material may vary; zinc plating is also common)

Corrosion Resistance: Typically available with zinc plating or other finishes for protection against rust and corrosion.

Efficiency: Simplifies assembly by providing a pre-positioned threaded insert, reducing installation time and costs.
