• 
  Condition: used, carefully inspected and tested for threading and fit; may show minor cosmetic wear but remains functionally solid for typical fastening tasks.

Ideal applications — this M5x16 screw is well-suited for a range of lightweight to medium-duty tasks, including:

• Electronics enclosures, chassis, and dashboard assemblies where a tidy, unobtrusive head is preferred
