DIN 985 M3 Nylock Nut (A2)

DIN 985 M3 Nylock Nut – A2 Stainless Steel

The DIN 985 M3 Nylock Nut is a precision-engineered self-locking nut designed to provide secure, vibration-resistant fastening in demanding environments. Built to the DIN 985 standard, this nut features a nylon insert that deforms elastically over the mating threads, creating a strong resistance to loosening without damaging the bolt.

Key Features:

• Thread Size: M3 x 0.5mm (coarse pitch)
• Material: A2 Stainless Steel (AISI 304) – excellent corrosion resistance, suitable for outdoor, marine, or damp environments.
• Locking Mechanism: Embedded nylon ring (polyamide) resists loosening from vibration, thermal cycling, or dynamic loads.
• Height: Reduced compared to standard hex nuts, making it ideal for tight space applications.
• Temperature Range: Up to ~120°C continuous use (due to nylon insert).
• Reusable: Can be reused a limited number of times; however, locking efficiency may decrease with each reuse.

Applications:

• Precision engineering and electronics
• Automotive and aerospace components
• Small mechanical assemblies and 3D-printed projects
• Robotics, drones, and hobby builds
• Corrosion-sensitive environments where non-rusting hardware is critical

Standards and Compliance:

• Standard: DIN 985 / ISO 10511
• RoHS Compliant: Yes
• ISO Metric Threads: Compatible with ISO metric bolts and screws
