Self-Drilling Design – Sharp point and thread design enable direct penetration into gypsum board, cement board, insulation board, and other lightweight substrates. No pre-drilling required, saving significant installation time and labor.
Why Choose Our Gypsum Board Expansion Screws?
Traditional self-tapping screws often fail in lightweight materials-they pull out easily under minimal load.
Our expansion screw set solves this problem: the internal expansion structure spreads like a butterfly or shell inside the cavity, creating a mechanical interlock that holds significantly stronger than standard screws.
Whether you are a contractor outfitting an office building or a DIY enthusiast hanging shelves at home, this product delivers the reliability and ease of installation you need.
Q: Can you provide official certificates, third-party inspection and reliable after-sales support?
Pain: Many suppliers provide fake or incomplete documents. Non-compliant goods get detained at customs with expensive detention charges. Suppliers often shirk responsibilities once quality defects appear, leaving you losing both goods money and shipping cost.
Answer: Honesty is our core business principle. All goods are produced per DIN/ISO/ANSI standards. We supply factory test reports and third-party inspection documents as required. If defects result from our production, we never avoid obligation and negotiate proper after-sales solutions actively for you.
