9/16-18 chrome lug nuts for aftermarket wheels with a 60° cone seat, designed to provide secure wheel fastening with clean, precise threads. Each lug nut is 2" (51mm) long and 0.91" (23mm) wide with a closed-end design to help keep dirt and moisture out. Made from cold-forged, heat-treated SCM 435 steel with a durable surface treatment to resist rust and reduce the risk of stripping during installation. Package includes 32 lug nuts plus 2 duplex hex socket keys for 13/16" (21mm) and 7/8" (22mm) hex sizes. Hand wrench installation is recommended; avoid powerful impact tools, confirm 5–7 full turns before tightening, torque to the vehicle’s stock specification, and re-torque after 25–50 miles and again after 1,000–2,000 miles. Not compatible with OEM wheels, mag seat, or ball/round seat applications.
