Fractional Sizes Slotted Castle Nut with Clear Zinc Cr3 Plating
Slotted Castle Nuts with Clear Zinc Cr3 Plating
Slotted castle nuts with clear zinc Cr3 plating are precision-engineered locknuts designed for secure fastening in high-vibration and high-load environments. These specialized fasteners are widely used in automotive, aerospace, construction, and heavy industrial applications where safety, reliability, and corrosion resistance are essential. The combination of a mechanical locking design and environmentally friendly clear zinc Cr3 plating delivers long-lasting performance in demanding conditions.
Key Specifications of Slotted Castle Nuts with Clear Zinc Cr3
Material Construction
Slotted castle nuts are commonly manufactured from carbon steel, alloy steel, or stainless steel. Carbon steel provides strong load-bearing capability, alloy steel offers enhanced toughness and impact resistance, and stainless steel delivers superior corrosion resistance for aggressive or moisture-prone environments.
Thread Sizes and Compatibility
These fasteners are available in a wide range of metric and imperial thread sizes. Common metric sizes range from M6 to M100, while imperial options typically span from 1/4" to 1" Fractional. This broad size range ensures compatibility with numerous bolts, shafts, and mechanical assemblies.
Slotted Locking Design
The defining feature of a castle nut is its evenly spaced slots at the top of the nut. These slots align with a pre-drilled hole in the bolt or shaft, allowing a cotter pin or safety pin to be inserted and physically lock the nut in place.
Clear Zinc Cr3 Plating
Clear zinc Cr3 (trivalent chromium) plating provides effective corrosion resistance while meeting modern environmental standards. This finish protects against rust, oxidation, moisture, and mild chemical exposure, all while offering a clean, professional appearance.
How Slotted Castle Nuts Provide Secure Locking
Cotter Pin Locking Method
After the nut is threaded onto the bolt and tightened to specification, one slot is aligned with the bolt hole. A cotter pin is inserted and bent into place, preventing rotation and loosening caused by vibration or dynamic forces.
Common Applications
High-Vibration and Safety-Critical Uses
Slotted castle nuts with clear zinc Cr3 plating are commonly used in automotive axles and steering systems, aerospace assemblies, heavy machinery, construction hardware, and industrial equipment.
Reliable, Corrosion-Resistant Fastening
Slotted castle nuts with clear zinc Cr3 plating offer a proven, secure fastening solution. Their mechanical locking design and corrosion-resistant finish make them ideal for applications where long-term stability and safety are critical.
