Butterfly screw GN 431-30-M6-16 Z011722

Butterfly screws – precision and convenient assembly

Butterfly screws GN 431 are fastening elements that combine functionality and ease of use. Made of stainless steel, they provide durability and corrosion resistance, making them an ideal choice for both indoor and outdoor applications. Their characteristic wing shape allows for quick and convenient assembly and disassembly without tools, which is particularly appreciated by installers.

Construction and materials

The screw body is made of sintered stainless steel AISI 316L with a matte sandblasted surface, which ensures an aesthetic appearance and abrasion resistance. The screw thread is made of stainless steel AISI 304, also with a matte sandblasted surface. An additional transverse pin secures the thread, preventing the screw from accidentally loosening during operation. This combination of materials guarantees high mechanical strength and resistance to aggressive environments.

Applications and benefits

Butterfly screws GN 431 are widely used in many industries, including:

• Mechanical engineering: mounting panels, covers, structural elements.
• Food industry: applications requiring high hygiene and corrosion resistance.
• Construction: assembly of facade elements, railings, supporting structures.
• Furniture: mounting furniture elements, adjusting settings.
• Medical devices: applications requiring high purity and safety of materials.

Thanks to their construction and material properties, GN 431 screws offer a number of benefits:

• Quick assembly and disassembly: no need for tools reduces working time and facilitates device servicing.
• High strength: stainless steel ensures long-term reliability even in harsh operating conditions.
• Corrosion resistance: ideal solution for outdoor applications and in environments with increased humidity or aggressive chemicals.
• Aesthetic appearance: the matte sandblasted surface gives the screws an elegant look that blends well with various materials and colors.
• Safety of use: Thread securing with a transverse pin minimizes the risk of the screw loosening spontaneously during operation of the device or structure.

The thread diameter is M6, the length (L) is 16 mm, the wing width (B) is 20 mm, the wing thickness (S) is 5 mm and the flat key size is 10 mm.
