Small 6 Point Spline Lug Nuts Key Tuner Socket Tool -Diameter Lock Lug Nut Key Compatible with 3/4" (19mm) and 13/16" (21mm) Hex Replacement Socket M12x1.5, M12x1.25, 1/2-20, M10x1.25, 3/8-20

It fit the lug nuts perfectly on my 1971 Chevy Chevelle SS.

Product as Described. Perfect fit and works great.

Very nice unit, unfortunately I ordered the wrong size and had to return. Always thankful for the easy Amazon returns!

Update: Amazon sent a replacement and it was not dented and works fine. ----- As described, however mine came with a slight dent in the end so I really had to hit it to get it to seat on the lug nuts. I don't know if it's possible to make it stronger given how thin it is - if your wheels have space for a thicker impact-compatible tool, that is probably the better choice. Notes to the vendor: - improve the packaging with an additional layer of bubble wrap to avoid shipping damage - change the package labelling - current label says 5-point for SKU X0042GD3QH but this is the 6-point model

It works fine on the appropriate lug nuts.
