Import Drilling Screw — Buy in Bulk from Supplier in China

The drilling screw offered by Hangzhou Lizhan Hardware Co., Ltd is a self‑drilling fastener with a hex washer head. It is made from zinc‑plated steel, a material that combines good tensile strength with corrosion resistance. The supplier provides a range of lengths and diameters to match diverse fastening requirements. The integrated washer distributes load and reduces the risk of pull‑through in both indoor and outdoor installations.

In the fastener market, zinc‑plated steel screws are standard for general‑purpose applications because they meet typical mechanical property grades such as 600 MPa tensile strength. Typical size ranges for similar products are 20‑80 mm in length and M3‑M8 in diameter, which align with the dimensions offered here. The hex washer head conforms to common tool standards, allowing use of standard hex‑wrenches without special adapters. These characteristics make the screw suitable for construction, HVAC, and automotive assembly work.

Buyers such as contractors, equipment manufacturers and maintenance firms often source these screws in bulk. The supplier indicates that minimum order quantities can be negotiated and that trade terms such as FOB and T/T are commonly used. Importers should confirm the exact packaging format - bulk cartons or poly‑bags - and request any required material test reports before shipment.
