The Dayton Parts 13-1720 is a high-strength metric wheel lug stud designed for heavy-duty commercial hub and drum assemblies. Engineered specifically for Gunite applications, this stud is manufactured from premium carbon steel and heat-treated to Grade 8 equivalent standards to ensure maximum safety and structural integrity under extreme load conditions. Each stud undergoes rigorous proof-load tensile testing and extensive salt-spray evaluation to provide a long-lasting, corrosion-resistant solution for your fleet.
SAE Grade 8 Strength: Meets the highest automotive industry standards for hardness and tensile strength, preventing shearing and stretching.
Corrosion Resistant: The durable black finish is tested against harsh road salts and chemicals to ensure years of rust-free service.
Metric Precision: Features M22-1.5 threads, the industry standard for modern hub-piloted wheel systems.
Optimized for Gunite Hubs: Designed for a precise press-fit with a specific shoulder diameter and knurl pattern to prevent stud rotation within the hub.
Trustworthy Quality: Backed by over a century of American expertise in heavy-duty truck component design.
