Description

Back Up Plate Washers are used with blind rivets for extra support when fastening into soft material. Useful for applications which involve thin or brittle materials where the risk of the fastener pulling through underload is significant. Available in zinc and aluminum.

• The zinc coating applied serves as a protective barrier against corrosion resistance.
• Made from steel.
• They provide a smooth bearing surface and protect the underlying surface from being damaged by the fastener.
• They maintain bolt tension and integrity by providing a smooth and uniform surface which reduces the likelihood of loosening due to vibrations.
• Commonly used in the automotive and marine industries for construction and manufacturing equipment.
