Value Collection 44697 M20 X 2.50 Hex Lock Nut Din 985

Product Description

The VALUE COLLECTION 44697 is a metric hex lock nut with a nylon insert locking mechanism, designed to resist loosening under vibration and dynamic loads. Built to Class 10 steel with a zinc-plated finish, this nut meets DIN 985 standards and is intended for M20 x 2.50 threaded fastener applications. The nylon insert compresses against the mating thread to create a prevailing torque that maintains clamp load without requiring additional locking hardware. It features a right-hand thread direction and is suited for mechanical assemblies, structural connections, and industrial equipment installations where fastener retention is critical.

This lock nut is used in commercial and industrial applications that demand reliable thread-locking performance on M20 fasteners. Typical install scenarios include equipment mounting, frame assemblies, and machinery where vibration or cyclic loading is present. It is installed by millwrights, maintenance mechanics, pipefitters, and general contractors working with metric-threaded hardware. The zinc-plated finish provides moderate corrosion resistance for light-duty indoor and sheltered outdoor environments. Sold individually with a minimum order quantity of 10 pieces.

• Right-hand thread direction, M20 x 2.50 thread pitch
• Minimum order quantity of 10 per order

Compatibility

Designed as a DIN 985-compliant replacement or service nut for M20 x 2.50 metric threaded bolt and stud applications in industrial and commercial mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using an appropriate metric wrench or socket sized to the 30 mm width across flats. Power down or de-energize any associated equipment before working on fastened assemblies. Nylon insert lock nuts are typically single-use and should not be reused once the nylon has been compressed by a mating thread, as locking effectiveness is reduced. Consult applicable mechanical or structural codes for required torque specifications based on application.
