Value Collection R52001678 Hex Lock Nut M14x2 Class 8

Product Description

The VALUE COLLECTION R52001678 is a metric hex lock nut with a nylon insert, designed to resist loosening under vibration and dynamic loads. Built from Class 8 steel with a zinc-plated finish for corrosion resistance, this nut features an M14x2 thread size and conforms to DIN 985 standards. The nylon insert provides prevailing torque locking without damaging mating threads, making it a dependable choice for mechanical assemblies, structural fastening, and equipment maintenance applications requiring a secure, reusable lock nut.

This nut is suited for use in industrial machinery, automotive assemblies, HVAC equipment mounting, and general fabrication work where metric fasteners are specified. The right-hand thread direction and DIN 985 standard compliance make it compatible with standard metric bolt patterns at M14x2 pitch. It is commonly used by maintenance technicians, millwrights, pipefitters, and fabricators working on metric-standard equipment across both light and heavy industrial environments.

Key Features

• Nylon insert locking style provides prevailing torque resistance without deforming the mating thread
• M14x2 metric thread size with right-hand thread direction
• Class 8 steel construction for reliable mechanical strength
• Zinc-plated finish adds corrosion resistance for general-purpose indoor and light outdoor use
• Conforms to DIN 985 fastener standard
• Reusable locking mechanism suitable for assemblies requiring periodic disassembly

Compatibility

Designed as a DIN 985-compliant nylon insert hex lock nut for use with M14x2 metric bolts and threaded rod in standard metric fastener applications.

Installation Notes

Installation is performed by hand tool or powered driver using a wrench sized for 22 millimeters across the flats. Ensure mating threads are clean and free of debris before installation to preserve the integrity of the nylon insert. The nylon insert provides a single prevailing torque element — inspect the insert condition if the nut has been removed and reinstalled multiple times in high-stress applications. No special certifications are required for installation, though follow applicable mechanical or structural codes for the assembly being serviced.
