Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh automotive environments.
- Precise 7/16"-20 thread fit ensures reliable engagement and prevents loosening under vibration and load stresses.
- 13/16" hex width provides ample torque application surface for secure, even clamping force on wheel assemblies.
- REACH (EC 1907/2006) compliance guarantees environmental safety and regulatory adherence for global supply chains.
- Heavy-duty durability from high-strength steel core, engineered for repeated use in demanding automotive applications.
- Enhanced wheel security through consistent dimensional accuracy, reducing risks of wheel detachment or misalignment.
Professional Applications & Engineering Value
This 7/16"-20 hex lug nut addresses critical challenges in wheel fastening systems by combining zinc-plated steel material with precision threading. The corrosion-resistant coating prevents rust formation in wet or salted road conditions, a common failure point in automotive nuts. Its 13/16" width allows for optimal torque transmission during installation, ensuring uniform pressure distribution across wheel studs. This design minimizes stress concentration and thread galling, particularly valuable in fleet maintenance and off-road vehicles where heavy duty lug nuts face constant mechanical shocks. By integrating REACH compliance, it also meets stringent environmental standards without compromising structural integrity, making it ideal for OEM and aftermarket applications requiring durable, corrosion resistant fasteners.
Specification Summary & Compliance
Manufactured to standard 7/16"-20 thread dimensions with Class 2A tolerance for consistent fit. The zinc-plated steel construction follows industry-grade specifications for hardness and shear strength. Fully compliant with REACH (EC 1907/2006) regulations regarding Substance of Very High Concern (SVHC) as of 01/17/2023, ensuring no restricted chemicals are used in production.
