Flange bolts are a common type of fastener with a wide variety of types. Here are some introductions to common flange bolts:
Hexagon Flange Bolts: Hexagon Flange Bolts are a type of hexagonal head bolt with a flange, which can increase the contact area between the bolt and the connected part, improve the stability and anti loosening performance of the connection, and are commonly used in fields such as automobiles and machinery. Hexagon flange bolts according to DIN 6921 or EN 1665 standards are available in two forms: full thread and partial thread, with or without serrations under the head.
Square Head Bolt with Collar: The square head design facilitates tightening and loosening operations with a wrench, while the flange provides a larger support area and enhances the reliability of the connection. It is generally used in situations where installation space and tightening torque are required.

Pallet Packaging

Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.

The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.

The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
