Description
Race Star M12 x 1.5 Closed Acorn Lug Nuts with Spline Head (10 Pack)
Precision-engineered spline-drive lug nut set designed for high-performance drag and street wheels with narrow lug sockets.
Overview & Performance Advantages
Upgrade your wheel installation hardware with the Race Star 603-1436-10 Closed Acorn Lug Nut Set. Engineered specifically for aftermarket drag racing and street alloy wheels, these lug nuts feature a slim-profile spline head that provides crucial clearance in tight lug bores where traditional hex sockets cannot fit.
Constructed from high-tensile alloy steel and finished in durable chrome, each lug nut utilizes a 60-degree conical acorn seat to deliver optimal clamping force, precise wheel centering, and superior vibration resistance under high launch and racing torque. The closed-end design shields stud threads from dirt, moisture, and road debris, ensuring long-lasting service life on both strip and street setups.
