proper lug nuts

[the big blue bus]

i am still using the stock acorn style lug nuts with my steel 15x10 wagon wheels. are these the correct style or should i be using the taperd ones? im planning on gettting some new longer ones to work with center caps i found and dont want to get the wrong kind. im not too sure they rounded ones are the right ones im using now

no idea, but I have an extra set if you get in a bind. Tapered witha spline drive

I wound up using longer acorn style spline chrome ones with my wheels, and no problems.
Got 'em from evil-bay

im looking at some black ones off ebay, the longer ones. when removing my wheel the other day i noticed one of them was messed up this is why im wondering if im suing the right type with these wheels
