Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- Sizes M3 to M36, parts WN25DPM03 to WN25DPM36 (Nord-Lock NL3SS-254 to NL36SS-254), with inner and outer diameter and thickness for each. For example M12: 12.8 to 13.2mm inside, 19.2 to 19.8mm outside.
- SMO 254 is an austenitic stainless steel made for maximum resistance to pitting and crevice corrosion.
- For high-chloride environments, saltwater solutions and atmospheres, and places where 316 stainless is not adequate.
- Secures bolted joints exposed to severe vibration and dynamic loads, for example rail, trains, motors and wind turbines. Lubrication does not affect the locking.
- A trace number is laser-etched on each washer.
Who it helps: Engineers and maintenance crews locking bolts in salty or chloride environments.
