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

Q1: Why is surface hardening required for stainless steel safety washers?<\/h3>
\n

Most stainless steel fasteners are relatively soft. To ensure the serrations can effectively “bite” into the bolt head and create a mechanical lock, the washer must have a higher hardness. Our process ensures a range of HV 350-550<\/strong>, making it suitable for high-tensile bolts.<\/p>\n<\/div><\/div>\n\n\n\n

Q2: Can I use S-series and M-series interchangeably?<\/strong><\/h3>
\n

S-series (Standard) is designed for regular bolts. M-series (Medium) has a larger outer diameter to reduce surface pressure, making it ideal for elongated holes or softer clamping surfaces.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
