Are lug nuts standardized?

[Joachim]

Are the lug nuts standardized across chevy trucks or is the threading different for various years. Can lug nuts from 80's & 90's be used on trucks from the 60's?

Steel wheels yes, newer "custom" style wheels no. The bolt pattern is the same, but back spacing is different on different years. The threads themselves may be the same, at least into the 80's, but I dont know about 90's, it seems they went metric on us.

Thanks for the info. The concern I had was that on the first look at the truck, I could not find the lug nuts. The wheels were off and the studs were rusted some. I took a second look-see this past Friday and found them in the cab under the seat. Tried one on the stud and with a little petro grease and a very little elbow grease they will go on just fine. Just waiting for the absentee owner to contact me to finalize the deal, take my money and drag her home !!
