Washer, M5 Spring Lock, Thin

Worked exactly as needed for a tight clearance spot where a standard washer wouldn't have fit. The thin profile is noticeably less bulky, and it held its tension well through a few disassembly cycles.

The thin profile fits perfectly where a standard washer would have bulged the assembly, and the spring tension holds firm even after a full day of vibration. Took a bit of sorting to find the right batch among my M5 hardware, but these are exactly what the machine needed.

M5 spring lock washers are annoyingly easy to get wrong, but this one fits the bolt without any wobble. The thin profile sits flush in my assembly, and it held tension perfectly through a quick vibration test.
