[datsunfreak]

Greatest thread title ever?

 

Least information given in a question ever?

 

:P

 

 

 

Gonna need more info than that, sir...

[phatdave]

I need a full set..20 lug nuts...and 4 lockers for my mags on my 73 620. Not sure what EXACT size of lug nuts to buy.....

[521Lvr]

well the lug thread pitch and size is 12mm x 1.25 on all nissan and datsun

not sure what style you need without seeing the wheels

hope that helps

If they're old school mags they need the shank type lugs, with washers. Just the regular ones at the parts store work.

'aholic.....I know the switch from SAE to metric happened on the 620, but wasn't the pre-disc trucks still SAE? I should remember this answer...I've given it before, but out of sight, out of mind.........hhmm...so everytime I'm out of sight, I'm out of my mind??? Sounds pretty accurate :)

Between the 521 and 510 is some of difference.

 

high beam circut

 

brake bleed are diff.

 

7/16 on the lug nuts

[datsunaholic]

620s all use the same lug nuts, Mike. I've swapped wheels, including the lugnuts, from my '78 to my Mom's '73 and vice versa. My 520, OTOH, I had to buy new shank lugnuts to put on mags (which didn't fit anyway, center hole is too small). But the lugnuts from ALL my 620s and all my '77 and later cars are the same thread.

take the wheel to a wheel/tire shop tell them the thread pitch you need, they will help u with the rest...least if they have any idea what they are doing they should...

[mklotz70]

Thanks 'aholic.....I guess the switch to metric happened at the 620 model change. The 521 has 7/16" lug bolts.

 

The metric ones should be easy to find. Most parts stores...knecht's, even Joes...typically have a display with sample bolts mounted to it. Take a spare lug nut that fits your rig and try it on the samples to be sure. Also check out the depth of the wheel where the lug nut goes through....typically, aluminum wheels are a lot thicker and use the long shanked ones. I've seen a few mags with conical seats on them...they would use the cone style...doubtful you have that type of mag because it's usually a pressed in steel insert for the seat.....anyway.....you most likely need 12x1.25 shanked(shank will be approx 1/2" or so).

And you'll probably need 24 not 20, unless you've done a 5lug swap or something

I think he wanted 20 and then 4 locks. ;)

I called Americas tire and was told 12x1.25...so thanks to everybody for the help.

I am going to have the old rubber taken off and do,hopefully, a polish job that does them right.

Then a set of 205 50 and 265 50 treads.

[datsunfreak]

And pics when you're done... :D
