Carbon Steel Self-Tapping Screws
Product Overview
This product is made of a carbon steel substrate with a yellow zinc plating surface finish, and is a general‑purpose fastening accessory for home carpentry, furniture manufacturing, and light sheet metal assembly. Featuring a large thin round flat head with a standard PH Phillips drive recess, combined with a coarse wide thread and a self‑tapping sharp point in one integrated structure, it can be driven directly into wood, MDF, thin metals, plastics, and other substrates without pre‑drilling. The yellow zinc passivation coating provides basic rust protection, balancing practicality and cost‑effectiveness, and is widely suitable for indoor light fixing applications.
Product Applications
Furniture Production: Fixing cabinets, wardrobes, decorative panels, drawer back panels, and wooden door frames.
Interior Decoration: Installation of wood joists, gypsum boards, wall paneling, and decorative trim.
Light Assembly: Fastening thin steel sheets, aluminium trims, lighting fixtures, and plastic bases of small appliances.
Indoor Small Hardware: Shelving units, indoor door and window accessories, and other light‑load components.
Suitable for dry indoor environments only. Not recommended for outdoor use, high‑humidity kitchens/bathrooms, or coastal salt‑spray conditions.
Product Features
Thin Large Flat Head for a Smooth and Neat Finish: The widened ultra‑thin flat head offers a large bearing area, preventing crushing of decorative surfaces; after installation, the head sits flush against the board without the need for countersinking, ensuring a clean finished appearance.
Coarse Thread for Reliable Fastening: The coarse, wide thread combined with the sharp point ensures smooth driving and deep engagement with the substrate, providing strong pull‑out resistance and reducing the risk of stripping or loosening.
Phillips Recess for Broad Compatibility: The standard PH cross recess is compatible with common screwdrivers and power driver bits, enabling efficient installation without slipping, whether for manual or assembly line work.
Yellow Zinc Rust Protection with High Cost‑Effectiveness: The yellow zinc plating meets indoor rust protection requirements, offers a lower cost than stainless steel screws, and the distinctive colour facilitates easy sorting and identification.
Stable Strength and Durability: Formed through carbon steel heat treatment with balanced hardness, it resists breakage and head damage during tapping.
