Product Description

Product Description

Steel Castle Nut

Castle nut is a small but essential fastener with a threaded hole. It pairs with a bolt to secure parts together.
Thread: The internal thread matches the bolt's external thread. Common thread profiles include ISO metric and UTS threads.
Body Shape: Hexagonal nuts are most common due to their ease of gripping with tools. Other shapes include square nuts, wing nuts for hand tightening, and cap nuts for covering bolt ends.
Metal: Steel is widely used for its strength. Stainless steel offers corrosion resistance, while brass has special properties like electrical conductivity.
Sizes and Standards
Metric System: Specified by thread diameter and pitch, e.g., M10-1.5.
Imperial System: Specified by thread diameter and TPI, e.g., 1/4-20.
Applications
Mechanical Assemblies: Essential for fastening parts in machines, vehicles, and structures.
Construction: Used to fasten steel beams and wooden structures.
Advantages: Easy to use, strong, reliable, and widely available in various sizes and materials.
In short, nuts are versatile fasteners used in many industries, providing a strong and reliable connection.

Packing & Delivery

Bulk/Fiber Bag/Neutral packing

Carton/Box

Wood Pallet/Box

Bagged packaging is ideal for smaller quantities of fasteners. The fasteners are placed in durable plastic bags, which are then sealed to protect the contents from moisture and dust. Each bag is clearly labeled with product details and quantities. This packaging is easy to handle and transport for smaller orders, making it convenient for workshops and retail settings.

Boxed packaging offers a more structured solution for medium to large quantities of fasteners. The fasteners are packed in sturdy cardboard boxes, which provide additional protection against physical damage during transit. The boxes are designed to stack neatly, optimizing storage space. Each box is labeled with essential information, ensuring easy identification and inventory 

Palletized packaging is used for bulk shipments of fasteners. Multiple boxes or bags are securely strapped onto a pallet, creating a stable and easily transportable unit. This method is highly efficient for large-scale distribution and warehousing. Palletized packaging ensures that large quantities of fasteners can be moved quickly and safely using forklifts, reducing handling time and labor costs.
