This Fine Thread Zinc Plated Lug nut will fit your Trailer Idler Hub, Drum, Or Disc Rotor Studs with a 9/16” Diameter. Most Trailer Wheel Studs up to about 7,000-8,000lb Capacity will use ½” Studs and Lug Nuts, many 8 lug, 8,000lb-10,000lb Set ups will use this larger 9/16” Style though.
These Trailer Lug Nuts are an Open Style, Flat Lug Nut. Certain Wheels do better with a Coned Style Lug Nut, but Certain wheels do not. If your Traielr Wheels have a chamfered or tapered bore where the lug nut goes, as many Aluminum Rims do, then it's recommended to use a Coned Style Lug Nut. If your Trailer Wheels have a Flat surface for the Lug Nut, then the Flat Style Lug Nut like this one is preferred.
These are fine thread Lug Nuts, with a 9/16” – 18 thread size. The Zinc Plating on this Lug Nut Helps to protect it against corrosion and gives the exterior a nice silver finish.
