Value Collection 47413 M6 High Collar Split Lock Washer

Product Description

The VALUE COLLECTION 47413 is a metric high collar split lock washer designed to resist loosening under vibration and dynamic loads in bolted assemblies. Made from Grade 2 steel with an uncoated finish, this washer fits M6 screws and provides a reliable locking action between the fastener head and the mating surface. The high collar design increases the bearing surface contact compared to a standard split lock washer, helping to distribute clamp load more evenly. It conforms to DIN 7980, the recognized fastener standard for metric high collar split lock washers, making it a straightforward drop-in choice for applications requiring that specification.

This washer is used in mechanical, HVAC equipment assembly, electrical enclosure fastening, plumbing fixture mounting, and general industrial applications where M6 metric fasteners are specified. It is suited for both original equipment assembly and field maintenance work. Technicians and tradespeople working on equipment with metric fastener systems will find this washer compatible with standard M6 bolt and screw hardware. The uncoated finish is appropriate for interior or protected installations where corrosion resistance from a coating is not required.

Installation Notes

Install between the fastener head and the mating surface or flat washer, with the split ends oriented to bite into both surfaces as the fastener is torqued. Ensure the mating surface and fastener thread are clean and free of debris before assembly. This washer is intended for a single installation cycle and should not be reused once a fastener has been fully torqued and removed. Work to applicable mechanical or equipment manufacturer torque specifications for M6 fasteners.
