What Size Lug Nuts Does the 2025 Land Rover Defender Use?
From model years 2019 to 2025, the Land Rover Defender comes equipped with M14×1.5 mm thread lug nuts, a 13/16-inch hex drive, and a flat-seat interface with an integrated washer. OEM fasteners are typically made from standard steel alloys, which are prone to material fatigue, wear, and surface degradation over time.
During normal operating cycles, these lug nuts experience repeated tensile loading, thermal expansion, and environmental exposure. Gradual thread wear and seat interface instability can occur, reducing clamping force and causing suboptimal wheel-to-hub engagement.
- Wheel imbalance
- Vibration at high speeds
- Increased dynamic stress on wheel studs
Steel oxidation further accelerates thread friction loss, increasing the risk of lug nuts loosening, which is particularly critical for both on-road and off-road Defender use.
Are Aftermarket Land Rover Defender Lug Nuts Safe?
High-quality branded aftermarket Defender wheel nuts are engineered to meet or exceed OEM safety standards. BONOSS forged ISO Grade 12 50BV30 lug nuts provide superior strength, durability, and corrosion resistance compared to standard OEM hardware.
Key features:
- ISO Grade 12 proof load: 105,700 N, maintaining clamping force under extreme loads and repeated stress cycles.
- Impact resistance, hardness, and proof load testing: Ensures long-term structural integrity.
- Anti-theft design: 7-sided heptagon locking key adds security.
- Corrosion & scratch resistance: Salt spray resistance >500 hours; prevents mechanical or environmental degradation.
