Frequently Asked Questions
What thread size does lug nut 5556 use?
Part #5556 uses a 14x1.5 (M14 x 1.5) right-hand thread. It will not fit studs threaded 14x2, 14x1.25, 12x1.5, 12x1.25, or 1/2".
What size socket fits this lug nut?
The hex is 19mm, so a 19mm lug nut socket is required. A thin-wall socket is recommended to help avoid marring the wheel.
What is a 60° bulge acorn seat?
A 60° conical bulge seat has an extended tapered cone that centers the lug nut in the wheel’s lug hole and spreads clamping load across a wider surface than a standard cone seat. Use it only on wheels designed for a 60° conical seat.
Is this an open end or closed end lug nut?
This is an open end lug nut, so it clears longer or extended wheel studs that would bottom out inside a closed end acorn nut.
Important Fitment Information
Please confirm the 14x1.5 thread size, 19mm hex, 60° Degree conical seat, 0.827" overall height, and wheel mating surface before purchasing.
An incorrect thread size or seat style may result in improper wheel installation. Professional installation and tightening to the vehicle manufacturer’s recommended torque specifications are strongly recommended.
