Type D Threaded Inserts – Reliable Metal Threads for Wood Joints
Type D threaded inserts are a strong and practical solution for adding metal threads to wooden parts, making them ideal for assembling or repairing furniture, cabinets, shelving, and more. These inserts allow bolts or machine screws to be securely fastened into wood, providing a long-lasting, reusable connection that won’t strip or wear out like traditional wood screws.
Made from tough, zinc-alloy or steel materials with corrosion-resistant finishes, Type D inserts are built to last. Their design features sharp external threads that cut into the wood for a tight, secure fit, and a smooth internal thread that accepts standard machine screws or bolts. Once installed, they create a durable metal anchor inside the wood—perfect for knock-down fittings, flat-pack furniture, or anything that may need to be taken apart and reassembled over time.
Installing Type D threaded inserts is quick and simple. Just drill a pilot hole in your wooden component, screw in the insert with a flathead screwdriver or insert driver, and you’re ready to add a bolt or connector. The result is a clean, professional-grade joint that adds strength and stability to your build. These inserts are especially useful in softwoods or particle boards where screws alone may loosen over time.
Available in various sizes to suit different bolt diameters and wood thicknesses, Type D threaded inserts are a must-have for anyone working with wooden joints that need to be strong, repeatable, and easy to maintain. Whether you’re building new furniture or improving existing pieces, these inserts offer a dependable way to add threaded metal fittings to wood with minimal effort. Keep them in your workshop for a simple upgrade to your next woodworking project.
