Product Description

Product Description

Carbon Steel Hanger Bolt

Hanger screws, also known as double-ended screws or stud bolts, are specialized threaded fasteners with continuous threading on both ends. 

These screws feature a central unthreaded shank section between two threaded portions of equal or different lengths. 

Standard materials include carbon steel (grade 4.8/8.8), alloy steel (grade 10.9/12.9)

Common diameters range from M3 to M36, with lengths spanning 20mm to 3m depending on application requirements. They're widely used in construction, machinery, and piping systems where permanent threading is needed at both connection points. One threaded end typically anchors into materials like wood or concrete, while the other accepts nuts for component attachment. The dual-thread design allows adjustable tension control and vibration-resistant connections. Heavy-duty versions (grade 10.9+) serve in structural applications like bridge building and industrial equipment.  Corrosion-resistant variants feature hot-dip galvanizing or zinc-nickel plating for outdoor use. Installation requires proper torque sequencing to prevent thread stripping in softer materials.

Common standards include ISO 4017, ASME B18.31.2, and DIN 975 for dimensional specifications.

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.
