Metric Series


    ITW Shakeproof Group’s Metric Series Helical Lock Washers are available in three styles:

  • Regular Metric: Like its Standard sized Regular counterpart, the Regular Metric series lock washers are designed for metric dimension applications.

  • DIN 127-B Compliant: These washers comply with DIN 127-B specifications, which incorporate a lighter ID section than the Regular Metric part.

  • DIN 7980 Compliant: The Square Section metric washers meet DIN 7980 specifications, and due to its design, are ideal for use in confined areas.
