OEM Carbon Steel Round Hole Square Curved Washer

The square curved washer, also known as a wave washer or spring washer, is a type of lock washer that is used to apply a load or force to a fastener, such as a nut or bolt. Its curvilinear shape allows it to compress and expand, creating a spring-like tension that helps to prevent loosening or tightening of the fastener due to vibration or other external forces. The square shape ensures that it stays in place and does not rotate along with the fastener. It is commonly used in automotive, aerospace, and industrial applications where securing a fastener is critical to the safety and functionality of a system.

Material: Carbon steel hot dip galvanized to ASTM A153 /ASTM A123
