Product Details

Our DIN 577 Square Nuts are manufactured to deliver excellent performance and durability in a wide range of applications.

• White-Blue Zinc Plating: This standard finish, also known as clear zinc, involves electro-galvanizing the carbon steel nut and applying a clear or slightly blueish chromate conversion coating. This process provides good corrosion resistance for indoor or mild-to-moderate environments while giving the nut a clean, bright, and silver-like appearance.
• Robust Carbon Steel Construction: The core of the nut is made from high-quality carbon steel. We offer these nuts in various property classes, such as Class 4.8 for general-purpose fastening and higher strength classes like 8.8, 10.9, and 12.9 for more demanding structural and load-bearing connections. This allows you to select the appropriate strength to match your bolt and application requirements.
• The DIN 577 Square Advantage: The primary feature of these nuts is their square shape. The four flat sides provide a much larger gripping surface than a standard hex nut, which is excellent for tightening with a wrench and offers superior resistance to loosening. This design is particularly effective when the nut is seated in a square channel or against a flat edge, as it prevents the nut from turning while the bolt is tightened, making it ideal for blind assemblies.
• Standardized for Consistency: Manufactured in strict compliance with the DIN 577 standard, these nuts guarantee uniform dimensions, thread profiles, and quality. This ensures a reliable and consistent fit for repeatable and secure assembly across all your projects.

Product Features

Our DIN 577 Square Nuts are a preferred choice for their functional and robust design.

• Superior Rotational Resistance: The square shape is easily captured in channels or slots and locks firmly against flat surfaces, preventing the nut from turning during tightening.
• Large Gripping Surface: The four flat sides provide an excellent surface for wrenches, allowing for easy and high-torque tightening.
• Reliable Corrosion Protection: The White-Blue Zinc Plating offers good protection against rust and corrosion in mild to moderate service conditions.
• Cost-Effective and Versatile: An economical yet highly functional fastener suitable for a vast array of industrial, construction, and agricultural applications.
• Multiple Strength Options: Available in various steel property classes to meet the specific load requirements of your assembly.
• DIN 577 Compliance: Guarantees dimensional accuracy, quality, and interchangeability for all your fastening needs.

Product Applications

The unique characteristics of square nuts make them indispensable in many industries.

• Construction and Framing: Commonly used in timber and steel framing, foundation work, and other structural connections where the nut can be seated against a flat beam or in a channel.
• Machinery and Equipment Assembly: Ideal for use in machine frames and heavy equipment where the nut is placed in a slot to prevent it from turning, simplifying assembly.
• Railroad and Transportation: A traditional fastener in the rail industry for track bolts and other heavy-duty applications requiring high clamping force and resistance to vibration.
• Agricultural Equipment: Used in the assembly of farm machinery and implements due to their robust nature and ease of tightening in the field.
• Utility and Pole Line Hardware: Often employed in outdoor utility structures, electrical towers, and other infrastructure projects.
