Value Collection 47411 M4 High Collar Split Lock Washer 50 Pack

Product Description

The VALUE COLLECTION 47411 is an M4 high collar split lock washer manufactured from Grade 2 steel with an uncoated finish. Designed for use in metric fastener assemblies, the high collar profile provides increased bearing surface and improved resistance to loosening under vibration compared to standard split lock washers. The washer features an inside diameter ranging from 4.1 to 4.4 millimeters, a maximum outside diameter of 7 millimeters, and a thickness of 1.2 millimeters. It conforms to DIN 7980 standards. Mechanical contractors, maintenance technicians, and industrial assemblers install these washers as part of bolted joint assemblies requiring metric hardware.

This washer is suited for metric M4 screw applications in light mechanical assemblies, equipment maintenance, and general industrial fastening. The high collar design is commonly used where additional clamp load retention is needed. Each package contains 50 washers, and the minimum order quantity is 5 packages. These are appropriate for use in residential, commercial, and industrial equipment contexts wherever M4 metric fasteners are specified.

Installation Notes

Installation is typically performed by maintenance technicians, mechanical assemblers, or trade professionals working with metric fastener systems. De-energize and isolate any equipment before disassembling bolted joints. Place the split lock washer between the fastener head and the mating surface, with the split gap oriented per assembly requirements. Torque the fastener to the specification called out in the equipment service documentation rather than applying an assumed value.
