Value Collection 47410 M3 High Collar Split Lock Washer 50pk

Product Description

The VALUE COLLECTION 47410 is a metric high collar split lock washer designed for use with M3 screws in general mechanical fastening applications. Manufactured from Grade 2 steel with an uncoated finish, this washer features a helical split design that creates spring tension when compressed, resisting fastener loosening caused by vibration or thermal cycling. The inside diameter ranges from 3.1 to 3.4 mm, the maximum outside diameter is 5.6 mm, and the washer thickness is 1 mm. Conforming to DIN 7980, the high collar profile provides greater bearing surface and improved locking action compared to standard split lock washers. Each package contains 50 washers.

These M3 high collar split lock washers are suited for light-duty metric fastening in mechanical assemblies, electrical enclosures, HVAC equipment panels, and general manufacturing or maintenance applications. The DIN 7980 standard makes them appropriate for metric fastener systems commonly found in European-specification equipment and imported machinery. Technicians and maintenance professionals installing or servicing equipment with M3 fasteners will find these useful for maintaining clamp load integrity over time.

Installation Notes

These washers are installed by mechanical technicians and maintenance professionals as part of standard metric fastening assemblies. Place the washer on the fastener shank between the screw head and the mating surface before torquing. Ensure the split ends are not pre-opened or deformed prior to installation, as this reduces locking effectiveness. Always de-energize or lock out equipment before accessing fastened panels or assemblies in electrical or HVAC applications.
