Zinc Plated Carbon Steel Slotted Castle Nut

It features slots running along its side, which are designed to allow a cotter pin or other securing device to be inserted through the slots and a hole in the bolt or stud it is threaded onto, ensuring that the nut remains securely fastened and does not loosen under vibration or other forces.

The Zinc Plated Carbon Steel Slotted Castle Nut is a high-strength fastener designed for secure locking in dynamic or high-vibration applications. Featuring a castle-shaped head with pre-cut slots, this nut pairs with a cotter pin to prevent loosening under stress. The zinc plating provides excellent corrosion resistance, enhancing durability in harsh environments.

Key Features:

Material: High-quality carbon steel for superior strength and load-bearing capacity.

Finish: Zinc-plated for rust prevention and improved aesthetics.

Design: Slotted (castellated) top allows cotter pin insertion, ensuring a vibration-resistant assembly.

Thread Compatibility: Matches standard thread pitches (e.g., UNC/UNF, metric).

Standards: Complies with DIN 935, ISO 7035, or ANSI/ASME specifications (as applicable).

Applications:

Ideal for automotive, machinery, aerospace, and construction uses—particularly in wheel hubs, axles, suspension systems, and other critical joints requiring fail-safe retention.

Advantages:

✔ Secure locking mechanism with cotter pin.

✔ Zinc coating extends service life.

✔ High tensile strength for heavy-duty applications.
