The Teckentrup locking washer NSK is a screw locking element confirmed by years of validation, which prevents the failure of a screw connection, especially under dynamic loads. With the advanced NSK washer, you receive a locking element that meets the increased requirements in the field of screw locking.

Product advantages:

• Secures against loosening and loss of preload under high vibrations.
• Settling effects are compensated by the high spring effect.
• Tested screw locking function at low and high preload forces.
• Screw connections with short clamping lengths are reliably secured under dynamic loads.
• Reusable (max. 3 times).
• Optimal locking function for elongated hole screw connections (NSK B and NSK L).
• Protects the counter surfaces (the NSK washer does not rotate during installation).
• Easy to install, as it is a one-piece locking element.
• No formation of chips during installation due to the special tooth design.
• Low variation in tightening torques and friction values.

The locking elements were designed based on the tightening torques and structural guidelines of VDI 2230. Reliable screw locking for high-strength connections with standard head supports. The standard variant Form "M" is a cost-effective solution for constructions where transverse forces and settling amounts occur, and can be used for strength classes up to 8.8.

Note: for screws with strength class up to 8.8.
