Ever tried attaching a wooden sofa arm to a metal bracket with regular screws? They strip, they loosen, or you spend forever drilling pilot holes. These double ended threaded furniture screws solve that. Made from galvanized steel with a self‑drilling tip, they bite into wood on one side and thread into metal on the other – no extra nuts, no separate bolts. Perfect for building stair treads, repairing IKEA hacks, or securing lightweight shelves to metal studs. Just grab your hex driver and go.
Galvanized steel construction – Zinc coating resists rust and corrosion. Ideal for indoor use even in humid spots like basements or bathrooms.
Double ended threads – Screw into wood and metal from both sides. Creates a clean, hidden joint without nuts or washers.
Self‑drilling tip – No pilot holes needed for wood, MDF, or thin sheet metal. Saves time and keeps your drill bits sharp.
Metric sizes M4 to M10 – Choose the right thread diameter for your project. Lengths from 16mm up to 120mm available.
Works with standard hex drivers – Use any cordless drill or hex bit you already own. No special tools required.

No. These screws have a self‑drilling tip designed for softwoods, hardwoods (up to medium density), MDF, and thin gauge metal (≤ 2mm). Just align your parts and drive it in. For thick steel (over 2mm) or concrete, you should pre‑drill a pilot hole – these screws aren't meant for heavy structural steel.
The galvanized coating provides good rust resistance for indoor use, including humid areas like kitchens or laundry rooms. For full outdoor exposure (rain, direct soil contact), we recommend adding a rubber or neoprene washer to seal the entry point, or upgrading to stainless steel versions. Keep unused screws in a dry bag – moisture shortens coating life.
Match the thread diameter to the pre‑existing hole in your metal part (if any). For metal brackets with no hole, M5 or M6 is a good start for furniture. Length should be roughly 2/3 of your wood thickness plus the metal thickness. Example: 20mm wood + 3mm metal = choose ~16–18mm screw. For heavier loads (sofa frames, stair treads), go with M8 or M10.
Over‑torquing can strip the threads inside the wood or deform the metal hole. Stop as soon as you feel solid resistance. If the screw keeps spinning, you've likely stripped it – back it out, add a sliver of wood glue or a toothpick into the hole, then re‑drive carefully. A cordless drill with adjustable clutch set to low‑medium torque is your friend.
Absolutely. The double‑ended design locks wood and metal together without loose nuts that eventually rattle loose. Perfect for tightening loose sofa frames, dining chair legs with metal corner brackets, or reinforcing bed slats. For moving parts (like folding furniture), add a drop of threadlocker for extra insurance.
