Hefei SENOTECH New Materials Co., Ltd proudly presents our premium Zinc Plated Steel Screws Plastic Expansion Anchors, specifically engineered for masonry applications. Manufactured from high-quality PE material with an innovative anti-rotation design, these anchors offer exceptional holding power and effortless installation, making them the ideal fastening solution for contractors, builders, and DIY enthusiasts. With full size availability, we ensure you find the perfect fit for your project, backed by our commitment to reliability and cost-effectiveness since 2020.
Our expansion anchors combine a corrosion-resistant zinc plated steel screw with a durable PE plastic sleeve. The unique anti-rotation ribs prevent the anchor from spinning during screw insertion, ensuring a secure and steady fix into masonry substrates such as concrete, brick, and block. This design significantly reduces installation time and eliminates common frustrations like stripped holes or loose fittings.
Key Features & Technical Specifications
- Zinc Plated Steel Screw: Provides excellent corrosion resistance and high tensile strength, suitable for indoor and outdoor use.
- PE Plastic Sleeve: UV-resistant, flexible, and impact-resistant ensures long-lasting performance in varying weather conditions.
- Anti-Rotation Design: Ribs on the sleeve grip the hole tightly, preventing rotation and allowing for precise screw driving.
- Easy Installation: Simply drill the recommended hole size, insert the anchor, and drive the screw – no hammering or special tools needed.
- Full Size Range: Available in diameters M6, M8, M10, M12 and lengths from 30mm to 120mm to accommodate diverse load requirements.
- Versatile Application: Ideal for mounting shelves, electrical fixtures, curtain rods, HVAC equipment, and more onto masonry surfaces.

Frequently Asked Questions (FAQ)
-
Q: What is the recommended drill bit size for these anchors?
A: Refer to the technical table above. Generally, the drill bit diameter matches the anchor size (e.g., use an 8mm bit for M8 anchors). For concrete, use a hammer drill with a carbide bit. -
Q: Can these anchors be used in hollow brick or drywall?
A: They are designed for solid masonry. For hollow substrates, we recommend our specific hollow wall anchors. Please consult our sales team for alternatives. -
Q: Are the screws replaceable? Can I use my own screws?
A: The screws are included and matched to the sleeve. Using different screws may compromise performance. We supply assemblies for optimal fit. -
Q: What is the temperature range for outdoor use?
A: The PE sleeve remains stable from -20°C to +60°C. The zinc plated screw resists corrosion in normal outdoor conditions. For extreme environments, consider stainless steel options (available on request). -
Q: Do you provide samples before bulk order?
A: Yes, we offer free samples for evaluation, with the customer covering shipping costs. Contact us to arrange. -
Q: What is the standard packing quantity?
A: Typically 100 pieces per box for smaller sizes, and 50 pieces per box for larger sizes. Custom packing is available. -
Q: How long does delivery take?
A: For stock sizes, we ship within 7-15 working days after payment. Custom sizes may require 20-30 days depending on volume. -
Q: Do you have any certifications for quality?
A: We follow strict internal quality control procedures. While we do not claim specific certifications unless confirmed, our products meet international standards for performance and safety. Full test reports are available upon request.
