Conical Contact Washer NF25-511 & SN 70093 (Tooth Series)
Offering a performance-oriented array of Conical Contact Washers with tooth, these items are designed as per the standards laid down by STD NFE 25-211 & Siemens SN 70093. While the washer has a conical structure, they come with both a tooth mounting side as well as a top serrated side. Both of these deliver high powered circular locking thrust at the mounting side as well as the interior area of the bolt head or nut. The tooth mounting section as well as the top serrated side enhances the locking force, which reduces any chances of but loosening to zero.
