These USS flat washers are for maintenance and assembly professionals who need to spread fastening force across a surface. They fit between a fastener and the work surface to help reduce pull-through, support more even tightening pressure, and serve as spacers where needed.

Each washer is made of unhardened carbon steel with zinc plating. The washers have a 9/16 in. inside diameter and a 1-3/8 in. outside diameter, are identified for 1/2 in. applications, and are manufactured to ASME B18.21.1. This package contains 50 washers.

Key Features:

  • USS washer profile: Provides a broad bearing surface to distribute fastener force more evenly.
  • Zinc-plated carbon steel: Delivers a steel washer construction with a zinc-plated finish.
  • Vibration resistance: Helps reduce fastener loosening caused by vibration.
  • 50-piece pack: Supplies multiple washers for ongoing fastening and assembly work.

Choose these flat washers when your fastening work calls for a 9/16 in. ID, 1-3/8 in. OD USS washer to distribute load, add spacing, or help limit pull-through.
