Product Description

Product Description

Fish Scale Sleeve Expansion Bolt

Fish scale expansion bolts (also known as fish-scale wall anchors) are fastening systems designed for secure installation in concrete, masonry, or steel substrates. They feature a unique fish-scale pattern on the expansion sleeve, which expands radially when tightened to create a frictional grip and prevent loosening under vibration . One-piece variants consist of a single metal flap that expands directly into the hole, while three-piece or four-piece designs include multiple flaps for enhanced load distribution and anti-loosening performance . These bolts are typically made of carbon steel, stainless steel, or galvanized materials, with surface treatments like white zinc or color zinc plating to improve durability . They are widely used in construction, ceiling installations, and industrial applications requiring high stability, such as HVAC systems and building fixtures . The in-situ expansion mechanism eliminates the need for pre-drilling, reducing installation time and costs while ensuring reliable anti-loosening performance . Specialized variants, such as heavy-duty three-piece or four-piece fish-scale expansion bolts, are available for applications with extreme dynamic loads . Fish-scale expansion bolts are available in various sizes (M6–M20) and configurations, with options for self-locking, rotating flanges, or dual-flange designs to adapt to different materials and environments .

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.
