Packing & Delivery

Bulk/Fiber Bag/Neutral Packing

Carton/Box

Wood Pallet/Box

Bagged packaging is perfect for smaller quantities of fasteners. Each fastener is placed in robust plastic bags, sealed to shield contents from moisture and dust. Clearly labeled with product details and quantities, this packaging is easy to manage and ideal for workshops and retail environments.

Boxed packaging provides a structured solution for medium to large quantities of fasteners. These fasteners are housed in durable cardboard boxes, offering extra protection from physical damage during transit. With boxes designed for neat stacking, they optimize storage space. Each box is labeled with essential information, ensuring ease of identification and inventory management.

Palletized packaging is the choice for bulk shipments of fasteners. Numerous boxes or bags are securely strapped to a pallet, forming a stable, easily transportable unit. This method is exceptionally efficient for large-scale distribution and warehousing, enabling quick and safe movement of large quantities using forklifts, thus reducing handling time and labor costs.
