Gorilla Small Diameter (.80") Spline Drive 60° Conical (Acorn) M12-1.5 Lug Nuts (21138)

Many aftermarket wheels for Toyota trucks and SUVs have smaller diameter lug wells that are incompatible with stock lug nuts.

Gorilla Automotive Products' 21138 series of small diameter (.80") spline driven lug nuts are the ideal match for these wheels. We offer them in standard and extended thread versions, in your choice of chrome or black chrome, in sets of 4, 20 (for 5-stud wheels) or 24 (for 6-stud wheels).

The standard thread version is 1.36" tall. If your aftermarket wheels are aluminum, the thickness of the wheel may not permit sufficient thread engagement with these standard thread lug nuts, especially on the relatively short wheel studs of older Toyotas.

If this is the case, our 1.6" tall extended thread version may be the solution. Below its conical lug nut seat is a .25" (~6mm) extended shank to allow for additional thread engagement.

WHEEL COMPATIBILITY WITH EXTENDED THREAD LUG NUTS

To ensure extended thread compatibility with your wheels, the following conditions must be met:

  1. The wheel's lug bore must be wide enough to fit the .62" diameter extended shank!
  2. The extended shank must not bottom-out on the rotor when it is torqued to factory specifications - The compressive force must be borne by the lug nut conical seat, not by the extended shank!

PLEASE NOTE: These small diameter spline drive lug nuts require Gorilla's Standard Key for Small Diameter (.80") Spline Drive Lug Nuts (1921SD-KEY) for installation and removal. It is sold separately.
