Thats a 5 pk for $1.43!

Fastenal quoted me $8 each.

Its the little things like nuts I get exited about I guess lol

may be a differant grade of stainless,,i would call arp and get theirs with the harden nuts and the aircraft nylon..

dan,i get my ss nuts and bolts from mcmaster-carr,check them out online.

fixx
 

Be careful..those may be the softer stainless nyloc nuts that stripp at torque spec..merc ones are a silver goldish color and mcmaster are all silver..i would get the merc ones or the hardened arp ones..

Remember even if they are not the merc ones and he starts pounding waves and the mcmaster car ones pull their threads bye bye drive and the boat does a 180* spin and sinks..

if youre that worried about the strength of the ss, buy grade 8 steel plated nuts and replace them every year, regaurdless of 300 series, 400 series, the best you will find will equate to about a grade 5. As for the 5 nuts for $1.43, thats gott be a glitch. We get over $1 per pound for scrap! Five nuts has to be a couple pounds.

I may be missing something and i don't claim to know everything but why do these nuts have to be nasa grade when all the force is on the prop shaft/thrust bearing?

Cuz it's oso, where you need a medium duty freightliner to haul a 292 formula

This nut isn't for the prop. They hold the upper and lower halves together.

Makes more sense.couldn't get the link to load so i assumed when the concern was the prop at the bottom of the lake.my bad.but still seems like a deal.

Jesus I was just trying to share a deal! Maybe you guys should click the links.
They are discontinued nuts that were originally $21.00 for the 5 pk. Limited quanity.
I cleaned out two locations yesterday.. 40 nuts for $12!
Regular price would have been $168. $280 from Bam
Next time I`ll keep it top myself end sell em on ebay! :angry-smiley-038:

lmfao!!!!!!!!!!!!!!!!!!!! :d

i have been replacing the origional merc nuts with the ones from mcmaster-carr for years and i have not lost a prop,or a drive ,geeeze.

hey dan,thats quite a sack of nuts for the money,did they have any brass balls on sale?:lolhit::lolhit:

just what are you trying to say?

as usual you side step a direct question,i was sure right when i named you THE MOUTH FROM THE SOUTH.maybe you should buy a sack of those nuts,but im sure you would not know how to act if you had any.:lolhit::lolhit:

Trying to figure out how the nut holds the prop on while in forward? :party-smiley-004:

We ran a boat for about 2 miles wide open, prop fell off when we put it in neutral lol
