Product Description

Hexagon joint nuts, also known as hex coupling nuts or extension nuts, are important fasteners.

Basic Features: 

Common Materials:

Application Scenarios: 

They are long and hexagonal in shape, which allows them to be easily gripped and operated by standard wrenches, facilitating the realization of firm and stable connections. The inner hole is circular, used to match with bolts or screw - rods.

Carbon steel is a popular choice for general - purpose joint nuts due to its high strength and affordability. Stainless steel has excellent corrosion resistance, making it suitable for outdoor or humid environments. Brass is often used in electrical applications because of its conductivity and corrosion resistance. Aluminum is lightweight and corrosion - resistant, suitable for occasions where weight needs to be considered.

Hexagon joint nuts are mainly used to connect two threaded components, such as rods or bolts, effectively extending their length. They are widely used in construction, automotive, machinery manufacturing, pipeline systems and other fields

Packing & Delivery

Bag Packaging

Carton Packaging

Fasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.

For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.
