Description

Whether you are setting up a drag car with extended studs or replacing rusted hardware on your boat trailer, these 1/2"-20 Open End Bulge Acorn lug nuts are the reliable, heavy-duty choice. The Open-Ended design allows wheel studs to thread completely through the nut, a requirement for racing applications using long studs or wheel spacers. The Bulge Acorn seat features a widened clamping surface, ensuring a safe, secure fit on both aluminum alloy wheels and steel trailer rims. Finished in industrial Zinc Plating, these nuts resist corrosion from saltwater and road grime.*Always verify your specific vehicle year and wheel type before purchasing.*
