Product Description
SAE Steel Flat Washers
GRADE 8 STEEL - HARDENED
√ YELLOW ZINC CHROMATE PLATED
*Bulk
These washers will not crush or deform when torque is applied from the tightening of a fastener to the joining material.
- Medium carbon steel provides high tensile strength
- For distributing the load between the fastener and the bearing surface
- Helps to ensure the tightness of fasteners and aid in preventing them from loosening
- Relieves friction between fastener and fastening material
- Zinc coating is a sacrificial topcoat used to aid in protecting the base steel material from corrosion
