Features and Benefits
Flat washers are standard washers used for general-purpose fastening. They are placed under the head of a bolt or above a nut to distribute clamping force and prevent fasteners from pulling through materials.
PTFE (polytetrafluoroethylene) has excellent resistance to corrosion, chemicals and moisture and is ideal for high-heat and corrosive environments.
