Description

Castle Nuts Steel Zinc Plated 9/16-12 are locking fasteners designed to prevent loosening in vibration-heavy assemblies. These slotted (castle) nuts are engineered to work with standard bolts and cotter pins for a secure, maintenance-friendly fit.

Product Highlights

  • Material: Steel
  • Finish: Zinc plated for corrosion resistance
  • Size: 9/16-12 thread size
  • Type: Castle nut with castellations for cotter pin
  • Fit: Compatible with standard 9/16 inch bolts

Why Choose This Castle Nut?

With a durable steel core and protective zinc coating, these nuts deliver reliable locking performance in automotive, industrial, and equipment applications. The castellated design accepts a cotter pin to prevent rotation, making them ideal for securing critical assemblies where vibration or dynamic loads are present.

Usage and Benefits

  • Easy installation: Align, tighten to spec, insert cotter pin through the bolt, and secure.
  • Anti-loosening: The castle nut design provides a simple and effective locking mechanism when used with a cotter pin.
  • Durability: Steel with zinc plating resists corrosion in many environments.
