Grade 12.9 High-Strength Wheel Bolts \/ Lug Bolts<\/p>\n

These Grade 12.9 wheel bolts are specifically designed for wheel hub connections in passenger cars, commercial vehicles, and construction machinery. Manufactured from premium alloy structural steel (e.g., 40Cr\/42CrMo), they undergo quenching and tempering heat treatment and surface strengthening processes, achieving Grade 12.9 high-strength performance. They feature exceptional tensile strength, yield strength, and fatigue resistance, capable of withstanding extreme loads and alternating stresses under high-speed driving, rough road conditions, and heavy-duty operations.<\/p>\n

The bolts adopt high-precision rolled thread technology, with clear thread profiles and precise tolerances, ensuring tight fit with lug nuts to effectively prevent loosening and thread stripping. The specially processed flange head increases contact area, distributes clamping force evenly to avoid crushing of the hub surface, and enhances anti-loosening performance. Surface treatment options include Dacromet coating, hot-dip galvanizing, and high-corrosion-resistant color zinc plating, offering excellent rust, corrosion, and salt spray resistance for harsh environments such as humidity and salt spray conditions.<\/p>\n

The products strictly comply with standards such as GB\/T 3098.1 and ISO 898-1. Each batch undergoes hardness testing, tensile testing, torque testing, fatigue testing, and salt spray testing, with 100% inspection before delivery to ensure stable and reliable dimensional accuracy and mechanical performance, providing critical safety guarantees for vehicle operation. Custom specifications, thread types, lengths, and surface treatments are available to suit various passenger car, commercial vehicle, and construction machinery wheel hub systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
