These USS flat washers are for maintenance, construction, and repair buyers who need to spread fastening force across a surface. They fit beneath bolts or screws to help distribute tightening pressure, provide spacing, and help limit pull-through.

Each washer has a 9/16 in. inside diameter and a 1-3/8 in. outside diameter. The washers are made of unhardened carbon steel with zinc plating and are manufactured to ASME B18.21.1. This pack includes 100 flat washers.

Key Features:

  • Broad bearing surface: Helps distribute fastener pressure over a larger area.
  • Vibration resistance: Helps reduce loosening caused by vibration.
  • Spacer function: Provides spacing where needed in an assembly.
  • Zinc-plated carbon steel: Provides steel construction with a zinc-plated finish.
  • 100-piece pack: Supplies multiple washers for installation and maintenance work.

Choose these USS flat washers when your fastening application calls for 9/16 in. ID, 1-3/8 in. OD washers that spread load, provide spacing, and support secure assembly.
