Product Description

Precision Machined Chinese Standard GB39 Square Nut

GB39 Square Nut - High-Strength Fastening Solution for Industrial Applications

Product Overview

Our GB39 Square Nuts are precision-engineered fasteners designed for robust and reliable connections in heavy-duty applications. Manufactured in strict compliance with the Chinese National Standard GB39, these square nuts offer superior holding power and are engineered to mate perfectly with standard hex bolts and screws. They are ideal for situations where a wrench cannot easily access a standard hex nut, or where anti-rotation is crucial, such as in T-slot assemblies, machinery, and structural frameworks.

Key Features

Premium Material: Made from high-grade carbon steel (Grade 4.8, 8.8 available) or alloy steel, ensuring excellent strength, durability, and load-bearing capacity.
Corrosion Protection: Available in multiple surface treatments including Electro-Galvanized (Zinc Plated), Hot-Dip Galvanized (HDG), Black Oxide, and Plain/Unfinished, providing varying levels of rust and corrosion resistance for different environments.
Secure Non-Slip Design: The square shape prevents rotation when tightened against a flat surface or within a channel, simplifying assembly and enhancing safety in vibrating equipment.
Precision Machining: CNC-controlled production guarantees consistent dimensions, accurate threading, and smooth, burr-free edges for easy and safe handling.
Wide Compatibility: Conforms to GB39 standards, ensuring interchangeability with common metric bolts and suitable for use in international projects.
Versatile Application: The extended bearing surface distributes pressure effectively, reducing the risk of damage to connected materials.
