Sirius A2 304 Stainless Steel Hexagon Lock Nuts

The Sirius A2 304 Stainless Steel Hexagon Lock Nut in M4 is a small but dependable fastener suitable for light engineering, electronics, model making, and general assembly work requiring a compact, corrosion-resistant fixing. The M4 size offers slightly greater load capacity than M3, making it a practical choice for applications where a little additional holding strength is beneficial without significantly increasing overall fastener size.

Constructed from A2 grade 304 stainless steel, this lock nut resists rust and oxidisation effectively, ensuring long service life even in damp or outdoor conditions. The nylon insert creates a secure locking action that prevents the nut from loosening under vibration or movement, providing added reliability in assemblies subject to repeated stress or environmental exposure.

The hexagonal shape ensures compatibility with standard small-profile spanners and socket tooling.

Features and Benefits:
• A2 grade 304 stainless steel provides reliable corrosion protection
• Nylon insert delivers effective vibration-resistant locking performance
• Compact M4 size suitable for light engineering and precision assembly
• Hexagonal profile for use with standard tooling
