Stainless steel butterfly screw Z037535

Stainless steel butterfly screws, such as model GN 433, are fastening elements providing quick and convenient assembly without the need for additional tools. The design with an ergonomic shape and offset hub facilitates both tightening and loosening, which is particularly appreciated by installers during fast assembly.

Made of precision cast stainless steel – available in AISI CF-8 NI and AISI 316 A4 versions – they are characterized by high corrosion resistance. The A4 version is particularly recommended for use in aggressive environments, such as areas exposed to salt, chemicals or moisture. Sandblasted matte finish provides an aesthetic appearance and a pleasant touch.

GN 433 butterfly screws find wide application in many industries – from machine and device construction, through furniture making, to steel structures. They are ideal for mounting panels, covers, shields and elements requiring frequent disassembly and reassembly. Thanks to the variety of available thread sizes (M4, M5, M6, M8) and shank lengths, they can be adapted to almost any project.

• Quick assembly: Eliminates the need for tools, reducing working time and increasing efficiency.
• Corrosion resistance: Stainless steel construction guarantees long-term reliability even in harsh conditions.
• Ergonomic shape: Facilitates grip and screw operation, minimizing the risk of hand injury.
• Versatility: Wide selection of sizes allows for adaptation to different applications.
• Aesthetic appearance: Matte finish gives the product an elegant character.

Available parameter combinations include thread diameter (d2) and shank length (l), allowing for precise adjustment of the screw to specific mounting needs. It is worth paying attention to the dimension d1 (wing width) and b (wing thickness), which affect the comfort of use and tightening force. Different values of h1 and h2 define the height of individual structural elements of the screw.
