M16×1.5 Grade 4.8 Carbon Steel Black Oxide Slotted Castle Nut DIN 935

The M16 × 1.5 Slotted Castle Nut is a high-strength fastening component designed for applications requiring reliable locking performance and resistance to vibration. Manufactured with a hexagonal body and precision-machined slots, this nut is commonly used together with a cotter pin to provide a secure mechanical locking system, preventing accidental loosening during operation.

Produced from Grade 4.8 carbon steel, the nut offers excellent durability, strength, and dimensional stability. The black oxide surface treatment provides a uniform black finish while enhancing corrosion resistance and wear performance. Precision-cut internal threads ensure smooth engagement with mating bolts, allowing for consistent load distribution and secure fastening.
