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 or DP 21138ETSB

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 require a special socket (available separately below) that is much smaller in diameter than a standard lug nut socket to fit in those tight locations where standard lug nut sockets won't.

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.

Please Note: In the order options you will also see some black spline drive nuts from DP. Similar to Gorilla in fitment and quality; DP's black finish is slightly flatter in appearance than Gorilla's gloss finish.

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