M3 x 7.0mm Nord-Lock® Washer | A4 Stainless Steel | Vital Parts - NL-M3-7-A4
Where conventional washers may not provide sufficient security, this M3 x 7.0mm Nord-Lock® Washer | A4 Stainless Steel delivers a purpose-designed anti-loosening washer. Accurate sizing of 3.4mm ID x 7.0mm OD x 2.20mm thick helps ensure a controlled fit within the joint. A4 stainless steel construction makes this option suitable for general outdoor, processing and stainless fabrication applications. The wedge-locking action supports joint reliability without relying solely on friction between the threads.
What Are Nord-Lock® Washers?
Nord-Lock® wedge-locking washers are designed to sit beneath a bolt head or nut as a paired system. Their external serrations grip the joint surfaces, while the opposing cam faces allow movement only across the wedge profile. This geometry resists rotational loosening under vibration and dynamic loading.
Common Applications
- Laboratory Equipment: Useful on stainless frames and mechanisms where clean appearance and joint security are important.
- Light Fabrication: Supports reliable fastening on corrosion-resistant brackets, guards and fabricated components.
- Stainless Enclosures: Secures covers, brackets and control hardware where corrosion-resistant fixings are required.
- Packaging Machinery: Suitable for compact stainless equipment exposed to frequent cleaning and repeated operation.
