Engineered Marine Products 12-01820 Nylon Insert Lock Nut

The Engineered Marine Products 12-01820 is a nylon insert lock nut designed for demanding marine applications where vibration and constant motion can cause standard fasteners to loosen or fail. This precision-engineered lock nut features a durable nylon collar insert that increases friction on the screw threads, providing reliable locking performance in harsh saltwater environments.

Key Features:

• Nylon insert locking mechanism provides superior thread retention
• Marine-grade construction resists corrosion in saltwater conditions
• Prevents loosening from vibration, shock loads, and continuous motion
• Cost-effective locking solution for outboard motors and marine equipment
• Reusable through multiple applications while maintaining locking torque
• Manufactured by EMP using precision machining for consistent quality

This lock nut is ideal for securing critical fasteners on marine engines, propulsion systems, steering components, and other applications where fastener integrity is essential. The nylon insert creates a prevailing torque that keeps the nut securely in place while allowing for proper installation and removal with standard tools.
