WASHER - 4MMX10MMX1.5MM (Anderson SY105235)

A worn washer can allow fastener loosening under vibration, leading to component misalignment. This aftermarket replacement part references the Anderson catalog and carries the cross-reference number SY105235. It is a hardware washer, a thin disc placed under a nut or bolt head to distribute load. The plain mechanical function is to provide a smooth bearing surface and prevent galling. A concrete generic failure consequence is that a missing or crushed washer can cause the fastener to embed into the softer material, reducing clamp force. The listed spec is 5MM. Verify the serial number or application, then call (562) 693-7748.
