What is a Flange Washer?<\/strong><\/h3>\n

A\u00a0flange washer<\/strong>\u00a0(also called a\u00a0shoulder washer<\/strong>\u00a0or\u00a0flanged spacer<\/strong>) is a type of washer with an extended rim (flange) around its central hole. This design provides a larger bearing surface, improving load distribution and preventing fastener heads or nuts from sinking into soft materials. Flange washers are commonly used in applications requiring vibration resistance, insulation, or reinforcement of thin panels.<\/p>\n
