<VV> S10 lug nuts

[Seth Emerson]

Joel - This is the first I heard about the S10 need for the external threads for the caps. Now it makes more sense, because by the time Chevy started using the external plastic cap covers, all the lug threads had changed over to 12mm (Metric) threads. But the aftermarket finally came out with the appropriate lugs with 7/16" and 1/2" internal threads.
White Knight wheel accessories  P/N 2002S - is a 7/16" thread open end bulge nut with the 24mm threads on the outside for the cap.  (1/2" are available as well.
Custom Wheel Accessories         P/N 5301DSP has the 7/16 thread, the external threads and a 3/4" hex - P/N 5301D has a 7/8" hex - They also sell the caps
Gorilla does not list one in a 7/16" thread.

No, they were the aluminum S10 wheels.  See attached.
I'm starting to remember more now though.  I think I could find nuts to make them fit but there were no nuts that had a combination of the correct taper and the external threads to mount the center caps.  I think the center caps are held on by fake plastic lug nuts over the real nuts.  This memory is killing me.
Summary IIRC:  The wheels need 3 things to fit.  Correct 1) stud thread, 2) taper and taper diameter, 3) external threads to mount the center caps.  I couldn't find nuts that matched all 3.

I have a suspicion the wheels you were using were styled steel wheels, those still have the 45 degree taper.  I'm pretty sure the alloy S-10 wheels use the same bulge nut, I have a friend with a set on his Corvair, I can check if Jerry decides to follow up.

The S10 wheels were the wrong angle and I think they were quite a bit larger diameter where the taper met the nut.  The 7/16" bulge nuts I tried were generic ones from the local FLAPS that fit the Z-28 and IROC wheels perfectly.  I had a set of Z-28 wheels on a Caprice, my '67 Monza and I installed IROC wheels on the '65 Monza I took the S10 wheels off of.
