FAQ<\/strong><\/strong>s<\/h3>\n\n\n\n

Q1: Why is phosphate black finish important for these washers?<\/h3>
\n

For high-hardness spring steel, phosphate black offers a stable friction coefficient without the risk of hydrogen embrittlement often found in electro-plating, ensuring safe use with 12.9 grade bolts.<\/p>\n<\/div><\/div>\n\n\n\n

Q2: Can I use DIN 25201 washers on slotted or oversized holes?<\/h3>
\n

For such applications, we recommend using our SP (Large Outer Diameter) series to ensure sufficient surface contact and load distribution.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
