ryobi adventure 110E reel

[ronluvs2fish]

i bought this reel from a frienit is in mint condition and i plan on using it for shark fishing. im missing the jam nut that holds the handle on. does anyone know where i can get a M16 - 1.0 jam nut. it is almost impossible to find and the few places that can get are wanting me to buy in packs of 100. i only need 1 nut so paying $100.00 for 100 nuts is not gonna happen.
thanks for any info
