Packing & Delivery

Bulk/Fiber Bag/Neutral Packing

Carton/Box

Wood Pallet/Box

Our bagged packaging is tailored for smaller quantities of fasteners. Each fastener is meticulously placed in robust plastic bags, sealed to protect against moisture and dust. Clearly labeled with product details and quantities, this packaging is easy to manage and perfect for workshops and retail environments.

Our boxed packaging offers a structured solution for medium to large quantities of fasteners. Housed in durable cardboard boxes, these fasteners are protected from physical damage during transit. Designed for neat stacking, these boxes optimize storage space. Each box is clearly labeled with essential information, ensuring ease of identification and efficient inventory management.

Our palletized packaging is the ultimate 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, reducing handling time and labor costs.
