Key Features & Benefits at a Glance
- Superior vibration resistance with nylon insert locking that maintains secure fastening under dynamic loads and shock.
- High-strength Class 8 rating ensures reliable performance in demanding industrial applications with heavy torque requirements.
- Reusable locking capability allows for multiple installations without significant loss of locking force, reducing replacement costs.
- Temperature resilience up to 220°F for stable operation in varied thermal environments without compromising the nylon insert's integrity.
- Corrosion-resistant zinc-plated steel provides durable protection against rust and extends service life in harsh conditions.
- Standard external hex drive enables easy installation and removal with common tools, improving assembly efficiency.
- Coarse metric thread (M48x5mm) with Class 6H fit ensures quick engagement and reliable holding power in coarse-threaded assemblies.
Professional Applications & Engineering Value
This M48 nylon insert lock nut is engineered to address critical challenges in heavy machinery, construction, and automotive sectors where vibration-induced loosening can lead to equipment failure. The zinc-plated steel construction offers robust corrosion resistance, while the nylon insert deforms elastically to lock threads securely, preventing back-off under continuous stress. Compliant with DIN 985 and ISO 10511 standards, it ensures dimensional accuracy and interchangeability in metric coarse-thread systems. Ideal for bolted connections in vibrating environments, this lock nut provides a reliable, reusable solution that minimizes maintenance downtime and enhances operational safety in industrial settings.
Specification Summary & Compliance
This lock nut features a metric M48x5mm coarse thread with Class 6H thread fit for precise tolerance, adhering to DIN 985 and ISO 10511 manufacturing specifications. It is constructed from zinc-plated steel with a strength rating of Class 8, and complies with RoHS 3 (2015/863/EU) environmental standards, ensuring it is free from hazardous substances for safe use in regulated industries.
