Carbon Steel Self-Tapping Screws
Product Overview
The Phillips button head self-tapping screw is a universal self-tapping fastener designed specifically for board connections and structural fastening. This series utilizes a classic structure comprising a button head, a Phillips recess, and a sharp self-tapping thread. Paired with two mature surface treatment processes—mechanical galvanizing and yellow zinc plating—it balances installation convenience, connection strength, and environmental adaptability. It is widely applied in fields like furniture manufacturing, interior decoration, and hardware assembly, standing as one of the most commonly used fasteners in woodworking and lightweight structural installations.
Product Applications
Suitable for panel furniture assembly, fixing interior decoration bases, and hardware/electrical appliance assembly. The mechanically galvanized version can also be used in humid scenarios like semi-outdoor areas, kitchens, and bathrooms.
Product Features
Large Flat Head Design: Increases the load-bearing area, eliminating the need for washers, preventing the crushing of boards, and ensuring a flat and aesthetic connection.
Phillips Drive: Accommodates conventional Phillips tools, resists stripping out, and makes installation highly efficient and effortless.
Sharp Point Self-Tapping Thread: Requires no pre-drilling and can be driven directly into substrates like wood, thin metal, and plastics to create a firm connection.
Dual Coatings Optional: The mechanically galvanized version features zero risk of hydrogen embrittlement and stronger rust prevention; the yellow zinc version is highly cost-effective and suitable for humid environments.
