Value Collection 47419 M20 High Collar Split Lock Washer 10pk

Product Description

The VALUE COLLECTION 47419 is a metric high collar split lock washer designed for M20 screw applications in bolted assemblies that require resistance to loosening under vibration or dynamic load. Manufactured from Grade 2 steel with a bright uncoated finish, this washer conforms to DIN 7980 fastener standards. The high collar design provides increased bearing surface compared to standard split lock washers, helping distribute clamping force more evenly. Inside diameter ranges from 20.2 to 21.2 millimeters with a maximum outside diameter of 30.6 millimeters and a thickness of 4.5 millimeters. Each package contains 10 washers.

This washer is suited for general industrial, mechanical, and structural bolted connections using M20 hardware. Typical applications include machinery assembly, equipment mounting, and maintenance work in manufacturing and trade environments. The DIN 7980 specification makes it compatible with metric fastening systems common in European-standard and metric-spec equipment. Installers in mechanical, HVAC, and industrial maintenance trades will find this a straightforward drop-in component for M20 bolt-and-nut assemblies where vibration resistance is required.

Installation Notes

Install between the fastener head or nut and the mating surface with the split gap oriented away from the workpiece where possible. Power down or de-energize any associated equipment before servicing bolted connections on machinery or panels. Use the appropriate torque wrench for M20 hardware per the assembly specification of the equipment being serviced. Do not reuse visibly deformed or flattened lock washers.
