Sirius A2 304 Stainless Steel Hexagon Lock Nuts

The Sirius A2 304 Stainless Steel Hexagon Lock Nut in M16 is engineered for heavy-duty fastening applications where high load capacity and dependable vibration resistance are critical. The M16 size is commonly specified in structural steelwork, civil engineering, large machinery, and industrial fabrication, where robust and secure fixings are non-negotiable.

Crafted from A2 grade 304 stainless steel, this lock nut offers outstanding resistance to corrosion and oxidisation, making it well suited to challenging environments including coastal, marine, and chemically exposed settings. The nylon insert locking mechanism ensures the nut maintains a firm grip on the threaded fastener, resisting loosening even under significant vibration and dynamic forces.

The hexagonal profile provides excellent engagement with standard spanners and socket sets for straightforward installation.
