Product Description

The Hex Flange Lock Nuts, or Stover Flange Nuts, are crimped like Hex Top Lock Nuts and designed with a built-in washer. The crimped tops provide metal-to-metal gripping strength with male threads to prevent loosening. The washers give the nuts a wider clamping force — protecting the material being fastened.
