What are M14x1.5 lug nuts?
There are 2 numbers in lug nuts size. "M" is an abbreviation for Metric thread, "14" is the diameter of the stud and the number "1.5" is the thread pitch, which is the distance in millimeters between each thread.
Bulge Acorn Seat
Acorn lug nuts are named because they are similar to an acorn in shape. The term acorn refers to the head style of a lug nut. The type of bulge acorn lug nuts is the same as the standard acorn seat, but they provide over 6% more seating surface area. They are perfect for Chevy and Dodge.
Mag Style Seat with Flat Washer
The mag-style seat has a unique look which features a long thread with a flat washer seat, allowing them to sit flush against the wheel. Unlike the bulge acorn seat, the mag style sits flat on the surface of a wheel, perfectly fitting to the 2015-2018 F150, 2015-2019 Expedition, and Lincoln 2016-2018 MKX.
The conical seat is a common type of lug nut. Unlike the spherical seat ( known as the ball seat ), conical seats differ with their angled shape and take a 60-degree taper. They are often recognized as acorn lug nuts because they look fairly similar.
