Product Description

Product Description

Stainless Steel /Carbon Steel Drop In Anchor

Drop-in anchors (also known as drop-in expansion bolts) are fasteners designed to secure objects in concrete, masonry, or steel by expanding radially when tightened. Their core mechanism includes a threaded rod with a conical end and an expandable sleeve with slots or cutouts, which expand upon tightening to create a frictional grip and prevent loosening. Installation involves drilling a hole, inserting the bolt with the sleeve, and tightening the nut to cause the sleeve to expand and lock into the hole, requiring minimal drilling depth and clean hole preparation. These bolts are commonly made of carbon steel, stainless steel, or aluminum, with surface treatments like galvanization or electroplating to enhance durability. They are widely used in heavy-duty applications such as HVAC systems, building fixtures, and industrial equipment, where vibration resistance and high load-bearing capacity are critical. The drop-in design eliminates the need for pre-drilling, reducing installation time and costs while providing reliable anti-loosening performance. Specialized variants, such as hydraulic drop-in anchors, further enhance torque transmission and reusability for complex industrial connections. However, their effectiveness depends on proper hole preparation and substrate compatibility, making them unsuitable for applications with extreme dynamic loads.

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.
