The FEIN 42616046003 is a replacement locking ring designed for use with FEIN power tools. Locking rings serve as retention and securing components within tool assemblies, holding spindles, guards, or accessory attachments firmly in place during operation. This part is sourced directly from FEIN and is intended to restore a tool to proper working condition when the original ring is worn, damaged, or lost. Licensed repair technicians and tool service professionals are the typical installers of this component.
This locking ring is a FEIN genuine replacement part suited for power tool maintenance and repair applications. It is used in service scenarios where a tool has been disassembled for inspection or repair and the original locking ring requires replacement to ensure safe and reliable operation. Specific compatible tool models are not identified in the available product data.
Designed as an OEM-style replacement locking ring for compatible FEIN power tools requiring this retention component during service or repair.
Installation should be performed by a qualified tool repair technician familiar with FEIN power tool disassembly procedures. Always disconnect the tool from its power source and allow any stored energy to dissipate fully before beginning disassembly. Use manufacturer-approved service documentation when available to confirm correct installation sequence and component orientation. Improper installation of retention hardware can result in unsafe tool operation.
