APR Ball-Seat Lug Bolts (OEM Style) 27mm-47mm

APR Ball-Seat Lug Bolts (MS100171 - MS100186) are high-quality, steel-constructed fasteners designed specifically for Audi, Volkswagen, and other vehicles utilizing the factory-standard ball-seat interface. These bolts are available in a variety of lengths to accommodate everything from stock configurations to aggressive wheel setups using spacers. Finished in a durable black zinc coating, they provide a clean, discrete look while offering excellent corrosion resistance.

When installing wheel spacers, it is critical to use longer lug bolts to maintain the appropriate thread engagement for safety. APR offers these in sets of 10, allowing you to easily equip a single axle (front or rear) with the precise length required for your specific wheel and spacer combination.

Features:

• OEM Ball-Seat Profile: Specifically designed to match the radiused seat found on factory VAG wheels and high-quality aftermarket wheels like the APR A01.
• High-Strength Steel: Robust construction engineered to handle the torque and stresses of performance driving.
• Black Zinc Finish: Provides a professional aesthetic that blends into the wheel face while protecting the steel from the elements.
• Safety Minded: Essential for maintaining proper thread engagement when adding thickness to the wheel hub via spacers.
• Convenient Packaging: Sold in sets of 10 for flexible axle-by-axle fitment.

Length Selection Guide:

Safety Note: Always ensure you have a minimum of 7-8 full turns of thread engagement when tightening lug bolts. Hand-torque all bolts to your vehicle's factory specification (typically 90-100 ft-lbs / 120-140 Nm) and re-check torque after the first 50 miles of driving.
