E/T Style Conical Head: 3/4" Hex with 1/2"-20 Threads. This 5-Lug Kit includes 20 chrome lug nuts and 4 chrome valve stems for installation of Legendary 5-lug alloy wheels. This smaller 3/4" Hex allows more clearance than traditional 13/16" Hex which helps prevent sockets from scratching wheels. This Kit is compatible with all Legendary Wheels on cars that have 1/2"-20 threaded studs.
