M5 Wing Nut DIN 315 -A4 Stainless Steel (316 Marine Grade) -22.5mm Wide

At 22.5mm wide, the M5 AA4 Stainless Steel Wing Nut is a popular general-purpose size -also known as a butterfly nut or thumb nut, manufactured to DIN 315 and designed for general light engineering, adjustable furniture, display systems and equipment covers where regular hand access without tools is a practical requirement. The two large wings allow the nut to be tightened and loosened by hand without any tools -essential wherever the fastening needs to be adjusted, inspected or removed regularly without stopping to find a spanner.

Manufactured from A4 stainless steel (grade 316) -also known as marine grade -this wing nut contains molybdenum which significantly enhances resistance to chloride corrosion compared to standard A2. At this small size the A4 grade is typically chosen for marine instrument housings, coastal electronics enclosures and precision assemblies in food processing or chemical environments where saltwater or cleaning agents are present. DIN 315 compliant -fits any compatible metric M5 bolt or threaded rod with a 0.8mm pitch.

Common Applications

  • Adjustable furniture and shelving system hand-tightened fastening
  • Display stand and exhibition system finger-tight fixing
  • Light machinery guard and access cover tool-free retention
  • General engineering assemblies requiring frequent manual adjustment
