The AEROQUIP Alum #16 Locknut (FCM2106) is a precision-engineered aluminum fastener designed for high-performance hydraulic and fuel system applications. This component is essential for securing hose fittings in environments where vibration, thermal cycling, and pressure demand reliable clamping force. It is particularly useful for mechanics working on custom vehicles and engine modifications.
Constructed from aluminum, this locknut offers corrosion resistance and lightweight properties, making it ideal for performance applications. The #16 size (approximately 5/16") is compatible with industry-standard SAE hose couplings and AN fittings. Its design ensures a secure grip under extreme conditions, although the specific locking mechanism is not detailed in the product data.
This locknut is perfect for builders upgrading fuel delivery systems or installing custom fuel pressure regulators. Its lightweight construction helps reduce overall system weight without sacrificing performance. Whether you're working on a fuel injection system or hydraulic lines, this locknut is a reliable choice for high-performance applications.
