Overview

DIN315 Stainless Steel 304/316 Wing Nut Butterfly Nuts are specialized fasteners designed for ease of manual operation without the need for tools. They are characterized by their distinctive “butterfly” or “wing” shape, which provides a large surface area for a user to grip and turn the nut by hand. Manufactured according to the German industrial standard DIN315, these nuts are typically produced from high-quality stainless steel grades 304 (A2) or 316 (A4), ensuring excellent corrosion resistance, durability, and a clean finish. The design allows for quick assembly, disassembly, and adjustments in various applications.

Advantages

• Tool-Free Operation: The most significant benefit is the ability to tighten and loosen the nut by hand. The prominent wings provide ample leverage and a comfortable grip, eliminating the need for wrenches or other tools, which is ideal for applications requiring frequent adjustments.
• Superior Corrosion Resistance:
  • Stainless Steel 304 (A2): Offers excellent resistance to oxidation and many corrosive agents, making it suitable for general outdoor and industrial applications.
  • Stainless Steel 316 (A4): Provides even greater corrosion resistance, particularly against chlorides and saltwater, making it the preferred choice for marine, coastal, and highly corrosive chemical environments.
• High Durability and Strength: Both 304 and 316 stainless steel grades offer good mechanical strength and wear resistance, allowing the nuts to withstand repeated use and moderate clamping forces without significant deformation.
• Standardized Dimensions: Adherence to the DIN315 standard ensures consistent dimensions, thread quality, and overall form, providing reliability and interchangeability with standard bolts and threaded rods.
• Aesthetic Appeal: The inherent sheen of stainless steel, combined with the distinctive butterfly design, offers a visually pleasing component, which can be an advantage in exposed applications.
• Versatility: Suitable for a broad spectrum of applications where quick and easy adjustments, assembly, or disassembly are recurrent requirements.

Application

• Furniture Manufacturing: Commonly used in knock-down furniture, adjustable tables, chairs, and other furniture components where parts need to be frequently assembled, disassembled, or adjusted by hand.
• Industrial Machinery and Equipment: Ideal for securing guards, access panels, covers, and other components that require regular removal for inspection, cleaning, or maintenance in industrial settings.
• Photography and Audiovisual Equipment: Extensively used on tripods, light stands, camera rigs, microphone stands, and other studio or field equipment for quick and secure adjustments.
• Laboratory and Medical Devices: Employed in various laboratory setups, scientific instruments, and certain medical equipment, particularly where non-corrosive, easy-to-adjust fasteners are essential for hygiene and functionality.
• Building Temporary Structures and Displays: Useful for assembling temporary displays, exhibition stands, shop fixtures, and signage where quick and tool-free setup and breakdown are necessary.
• Marine and Outdoor Applications: Especially those made from Stainless Steel 316, these wing nuts are perfect for boats, docks, outdoor furniture, and other applications exposed to weathering, moisture, or saltwater.
• DIY and Hobby Projects: A favored choice for home improvement projects, crafts, and various hobbyist constructions due to their user-friendly design.
• Bicycles and Sports Equipment: Can be found on certain adjustable parts of bicycles (e.g., quick-release seat clamps) or other sporting goods where on-the-go adjustments are beneficial.
