Malaxy Wing Nuts (also known as Butterfly Nuts or Thumb Nuts) are a special type of fastener designed for quick, tool-free manual operation. The two protruding “wings” allow operators to tighten or loosen the nut by hand, significantly improving efficiency in applications that require frequent assembly, maintenance, or rapid adjustment.

Key Advantages

• Tool-Free Operation – The winged design enables fast hand tightening in confined spaces or at heights, eliminating the need for wrenches or sockets.

• Dual Standard Compliance – Available in both DIN 315 (Metric) and ASME B18.6.9 (Inch/Unified) standards to meet global market demands.

• Multiple Material Options

  • Stainless Steel A2-70 (304) – Suitable for indoor, dry, or mildly corrosive environments. Widely used in electronics, electrical enclosures, and general industrial equipment.

  • Stainless Steel A4-80 (316) – Ideal for highly corrosive environments such as marine, chemical, acidic media, and chlorine-rich conditions.

  • Zinc-Plated Carbon Steel – Cost-effective solution with good rust resistance for indoor equipment and light outdoor use.

• Wide Size Range – Metric M3 to M24 (expandable to M30) and Inch #5 to 1/2″. Custom thread sizes and surface finishes (hot-dip galvanized, black oxide, Dacromet, etc.) are available on request.

Main Applications

• Furniture Assembly – Office furniture, laboratory workbenches, display racks, and other scenarios requiring frequent disassembly.

• Machinery & Equipment – Access panels for automation equipment, conveyor clamping devices, and equipment maintenance access points.

• HVAC Systems – Duct connections and access doors for air handling units and ventilation systems.

• Electrical Enclosures – Distribution cabinets and industrial control panels that require frequent inspection and maintenance.

• Agricultural Equipment & Temporary Structures – Exhibition booths, stage trusses, photographic equipment, and agricultural machinery repair.
