Spline Drive E/T Ultra Style Conical Lug Nuts 12mm X 1.5 (Various Quantities)

Available In Sets of 4, 20 and 24 Pieces

GOR 21138ET or GOR 21138ETBC

A premium bulge acorn lug nut from Gorilla with their super tough chrome or black chrome finish. 12mmx1.5. A problem solver for a lot of customers. These nuts feature a small diameter body with a spline drive profile.

These nuts are a little harder to find at tire or parts stores, they feature an extended thread section/centering barrel that increases thread contact and helps center the wheel even better than a standard acorn style nut. Not all aftermarket wheels will be able to use this type of nut with the extended thread section/centering barrel, check the dimensions in the image to determine if these are correct for your wheels.

We sell these in packages of 4, 20 and 24 lug nuts.

  • The spline drive sockets (GOR 1921SD-Key) for these are available separately
  • They are excellent for aftermarket wheels that have small diameter lug wells which don’t go good with Toyota’s big 13/16" hex size lug nuts. They also are great theft deterrents.
