🔩 Double Ended Threaded Furniture Screws – Connect Wood to Wood or Wood to Metal Without Nuts
Ever tried joining two pieces of wood without exposed bolt heads or needing a nut on the back? That’s where these double ended threaded dowels shine. Sometimes called wood to metal dowels or furniture connector screws, they screw into a pre-drilled hole on one side and leave a threaded stud sticking out to attach a leg, bracket, or another panel. No nuts required because both ends are self-tapping. Whether you’re building a bed frame, assembling cabinets, or repairing a chair, these M4 to M12 furniture screws come in a range of sizes (M4, M5, M6, M8, M10, M12) and two material choices: A2 stainless steel for rust resistance or zinc-plated carbon steel for everyday indoor use.
✨ Why Choose These Double Ended Wood Screws?
🔧 Double ended self-tapping design – Both ends cut threads into wood or soft metal; no nuts or washers needed for most applications.🪑 Ideal for furniture assembly & repair – Perfect for joining table legs to aprons, attaching bed rails, or making knock-down fittings.
🛡️ Two material options – Choose A2 stainless steel for moisture resistance (outdoor or humid shops) or zinc-plated carbon steel for budget-friendly indoor projects.
📏 Wide metric range M4 to M12 – M4 and M5 for delicate furniture, M6 and M8 for general woodworking, M10 and M12 for heavy structural connections.
📦 Comes in a plastic storage box – Keeps screws organized and protected; easy to grab the size you need without digging through loose bags.
⚙️ Precision machined for consistent threading – Smooth entry and strong grip, reducing splitting in hardwoods.

❓ Frequently Asked Questions – Double Ended Furniture Screws
🪑 How do I use these double ended threaded screws for wood to metal connections?
Drill a pilot hole slightly smaller than the screw diameter into the wood. Screw one end of the dowel into the wood until it’s flush or slightly recessed. The other end will stick out. For metal, you typically need a pre-threaded hole (or use a nut if the metal is thin). But most common use is wood-to-wood: both ends screw into separate wood pieces, acting as a hidden dowel that also pulls pieces tight.
🔩 Do I need nuts or washers with these screws?
No. Unlike standard bolts, these are designed as self-tapping dowels. The threads cut directly into wood or soft metals. However, if you're using them as a stud to attach a metal bracket, you might add a nut on the exposed end for extra security. For wood-to-wood joints, no nuts needed.
🌧️ Which material should I choose – stainless steel or zinc plated?
If your furniture will be outdoors (garden bench, patio table) or in a damp basement/workshop, go with A2 stainless steel – it resists rust much better. For indoor furniture like bed frames, bookshelves, or kitchen cabinets, zinc-plated carbon steel is perfectly fine and more economical. The zinc coating provides basic moisture protection for dry environments.
📏 How do I pick the right size (M4, M6, M8 etc.) for my project?
M4 (4mm diameter) is good for small furniture like jewelry boxes or chair spindles. M5-M6 is the most common for general cabinet and table assembly. M8 is heavy duty for bed frames or workbenches. M10 and M12 are for structural timber connections or large outdoor furniture. As a rule: thicker and heavier the wood, larger the diameter you need.
🧰 Does the plastic box come with all sizes or do I pick one size per box?
The product listing typically offers each diameter separately (e.g., a box of M6 screws). You can choose the specific size you need. The plastic box helps keep that size organized. If you need multiple sizes, you’d order separate listings or a mixed set if available. Check the variant selector above to see which diameter option you’re buying.
