Complete Kit – 6 Studs + 6 Matching Nuts:This upgraded set includes 6 wheel studs and 6 lug nuts – one full axle replacement kit. Thread: 1/2 -20 UNF. Stud total length: 2.06 (52.4mm). Thread length: 1.28 (32.6mm). Spline length: 0.59 (15mm). Spline diameter: 0.57 (14.48mm). Head diameter: 0.75 (19mm). All dimensions match OEM specifications for many 2000–3500 lb trailer axles. 10.9 Grade Steel – Built for 2000–3500 lb Trailers:Studs and nuts are forged from high‑strength 10.9 grade steel – providing superior tensile strength, wear resistance, and impact resistance. Specifically rated for trailers with axle capacities from 2,000 to 3,500 lbs (e.g., utility trailers, boat trailers, small campers, jet ski trailers). The matching nuts are heat‑treated for a perfect, secure fit. Serrated Spline & Precision Thread Design:The serrated spline (0.57 diameter) bites firmly into the hub, preventing rotation during tightening. The 1/2-20 UNF threads are precisely machined to avoid cross‑threading and loosening while towing. Nuts feature matching high‑precision threads for smooth torque application and consistent clamping force. Electroplated Coating – Rust & Corrosion Resistant:Both studs and nuts receive an advanced electroplating finish. This coating provides excellent protection against rust, oxidation, moisture, road salt, mud, and harsh weather – keeping your trailer’s wheel mounting reliable and clean for years, even in coastal or winter conditions. Wide Application – Ideal for Lippert & Other 2k‑3.5k Axles: Designed specifically for Lippert trailer axles and compatible with many other brands using 1/2 -20 wheel hardware. Perfect for replacing worn or damaged studs on utility trailers, boat trailers, small cargo trailers, and single‑axle campers. Suitable for both front and rear wheels. A must‑have for DIY mechanics and trailer owners seeking a complete, heavy‑duty replacement kit.
