🏷️ Brand: HomeDIYer Fastener | DIN7505A | A2-70 | Fully Threaded | Pozidriv Countersunk
📌 Overview — Strong, corrosion-resistant screws for chipboard, MDF, and solid wood. Tired of splitting wood or dealing with rusted screws on outdoor projects? Our A2 Stainless Steel Pozi Countersunk Chipboard Screws (DIN7505A) are engineered specifically for engineered wood, particle board, and natural timber. The sharp, deep threads bite quickly without pre-drilling in most softwoods and chipboard, while the countersunk head sits flush with the surface for a clean finish. The Pozidriv recess provides excellent driver grip and reduces cam-out, making assembly faster and frustration-free. Fully threaded from 3mm to 6mm diameters, these screws are ideal for cabinet making, decking, furniture assembly, and outdoor wood projects. Made from A2-70 stainless steel, they resist rust and staining, even in damp environments.

💡 Length & ordering info: Screws are fully threaded. Length includes the head (overall length). Choose your preferred length (e.g., 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 70mm, 80mm) — sold as per your requirement. Contact us for bulk or custom-length orders.
🔧 Compatibility note: These screws are designed for chipboard, MDF, plywood, and softwoods. As with most thread-cutting products, they will not cut materials harder than themselves (e.g., hard steel, concrete). For hardwoods, pre-drilling is recommended.
❓ Frequently Asked Questions – Pozi Countersunk Chipboard Screws
Do I need to pre-drill before using these chipboard screws?
🔧 For most chipboard, MDF, and softwoods, no pre-drilling is required — the sharp point and deep threads will self-tap. For dense hardwoods (oak, maple) or near edges, we recommend a pilot hole to prevent splitting. Always test on a scrap piece first.
What driver bit do I need for Pozidriv screws?
📐 Use a genuine Pozidriv (PZ) bit. Sizes: 3mm-3.5mm → PZ1, 4mm-5mm → PZ2, 6mm → PZ2 or PZ3 depending on length. Phillips (PH) bits will fit poorly and may slip or damage the recess. We strongly recommend PZ bits for best torque and minimal cam-out.
Are these screws suitable for outdoor use? Will they rust?
🌧️ Yes – A2-70 stainless steel (304 grade) provides excellent corrosion resistance for outdoor furniture, decks, garden structures, and coastal areas. They will not rust like carbon steel screws. For continuous saltwater immersion, consider A4 (316) stainless, but A2 is perfect for most exterior wood projects.
What lengths are available? Can I order custom lengths?
📦 “Package Included: As per Your Choice” means you select the exact length you need. Common lengths: 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 70mm, 80mm. Custom lengths available for bulk orders. Just let us know your requirement.
What is the difference between chipboard screws and standard wood screws?
🪵 Chipboard screws have deeper, sharper threads and a thinner core than standard wood screws, providing better grip in engineered woods like particle board and MDF. They also typically have a countersunk head and Pozidriv drive. They work excellently in solid wood as well, but are optimized for chipboard.
