Sirius A2 304 Stainless Steel Hexagon Lock Nuts

The Sirius A2 304 Stainless Steel Hexagon Lock Nut in M8 is a popular and reliable fastener for medium-duty engineering, construction, automotive, and fabrication tasks. The M8 size is frequently specified in frame construction, machinery assemblies, vehicle components, and racking systems, where a strong, vibration-proof fixing is essential.

Manufactured from A2 grade 304 stainless steel, this lock nut provides outstanding protection against rust, oxidisation, and general corrosion, performing dependably in both indoor and exposed outdoor environments. The nylon insert creates a firm self-locking engagement with the threaded bolt or stud, resisting loosening caused by vibration, mechanical shock, or fluctuating loads — an important characteristic in safety-critical or high-cycle applications.

The hexagonal profile ensures compatibility with widely available spanners and socket sets for efficient installation.

Features and Benefits:
• A2 grade 304 stainless steel delivers excellent long-term corrosion resistance
• Nylon insert resists loosening under vibration and mechanical shock
• M8 size widely used in engineering, automotive, and construction applications
• Hexagonal profile for straightforward installation with standard tooling
