SAE Flat Circular Washers Zinc Plated/HDG For Machinery
Flat Steel Washer Description:
Flat Circular Shape: SAE flat washers have a flat, circular design with a centrally located hole. This design allows for even distribution of the load from the fastener across a wider area, reducing the risk of damage and providing a secure connection.
Standard Dimensions: SAE washers adhere to specific dimensional standards set by the Society of Automotive Engineers, ensuring compatibility with SAE fasteners.
