WING NUT (DIN315)

WING NUT (DIN315)
A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without tools.

A similar fastener with a male thread is known as a wing screw or a wing bolt.

ASME B18.6.9 classifies wing nuts first by manufacturing method and then by style.

  • Type A are cold forged or cold formed produced in regular, light and heavy dimensional series.
  • Type B are hot forged solid nuts available in three different wing styles.
  • Type C are die cast nuts available in three wing styles with variances between regular and heavy dimensional series
  • Type D are stamped sheet metal nuts available in three wing styles.

PRODUCT APPLICATION

COMMON APPLICATIONS OF WING NUT:
  • Bicycle parts:  bicycle wheels were held in place with wingnuts.
  • In a drum kit wingnuts and wingbolts are used extensively.
  • For securing a suspended cymbal on the mounting bolt of a cymbal stand.
  • For securing an adjustment on a stand.In connection with memory.
  • Seltzer bottle; The device that surrounds a CO2 cartridge in a seltzer bottle is also a wingnut. Twisting the wingnut completes a seal around the cartridge neck; twisting a bit more causes a pin to pierce the cartridge and let the gas into the bottle.
