S-90576A144 M12 ISO 10511, DIN 985 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through the nylon insert that maintains locking force under continuous motion and shock loads
• Reliable high-temperature performance with the nylon insert rated for temperatures up to 220°F (105°C) without compromising locking capability
• Exceptional corrosion protection provided by zinc-plated steel construction, extending service life in harsh industrial environments
• Precision thread engagement with Class 6H thread fit ensuring consistent clamping force and reduced risk of cross-threading
• Heavy-duty load capacity meeting Class 8 strength requirements for demanding applications requiring high clamp load retention
• Standardized compatibility with ISO 10511 and DIN 985 compliance ensuring interchangeability and quality assurance
• Easy installation and removal with standard 19mm external hex drive compatible with common wrenching tools

Professional Applications & Engineering Value

This M12 nylon insert lock nut delivers critical vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where constant motion threatens fastener integrity. The zinc-plated steel construction provides essential corrosion protection for outdoor or humid environments, while the fine 1.5mm pitch metric thread offers superior clamping force distribution compared to coarse thread alternatives. Engineers specify this Class 8 strength locknut for applications requiring repeated disassembly and reassembly, as the nylon insert maintains consistent locking performance through multiple cycles without galling or thread damage. The combination of ISO 10511 and DIN 985 compliance ensures dimensional accuracy and reliable performance across European and international engineering standards.

Specification Summary & Compliance

This metric locknut features M12 x 1.5mm fine threads with Class 6H thread fit tolerance for precise engagement. Manufacturing complies with ISO 10511 and DIN 985 standards for dimensional accuracy and performance testing. The zinc-plated steel construction meets RoHS 3 (2015/863/EU) compliance for environmental safety, while the Class 8 strength rating validates mechanical performance under high tensile and vibrational loads. External hex drive (19mm width) ensures compatibility with standard metric wrench sets.
