Upgrading your wheels or need replacement lug bolts? This is a set of 10 black acorn-style cone seat lug bolts. The specs are: 12mm diameter with a 1.25mm thread pitch, and they have a 28mm long shank. The cone seat is crucial - it must match the contour of your wheel's lug holes (most aftermarket and many factory wheels use a cone/tapered seat). They're from xlugs.com, part number 841149-28BLK. They come with a manufacturer warranty and are brand new in the package. Placement is for all four wheels (front/rear, left/right). These are specifically mentioned to fit vehicles like the Fiat 500, Dodge Dart, and various Jeep models, but always double-check your vehicle's exact lug specifications before buying! The black finish gives a sleek, custom look, especially on black or dark-colored wheels. Much stronger and better looking than rusty old bolts. Perfect for when you're installing new wheels, restoring a car, or just want a cleaner aesthetic. Installation requires a lug wrench or socket. Don't risk your safety with wrong or worn lug hardware - get a complete matching set for peace of mind.
