How To Use Threaded Inserts and Bolts - Professional Table Leg Install

Hello, woodworking enthusiasts!

Whether you're crafting a dining table, a desk, or any other piece of furniture, ensuring that the legs are securely attached is crucial. In this guide, we'll walk you through the steps to install table legs for a sturdy and professional finish.

Why Proper Installation Matters:

A table isn't just a piece of furniture; it's a centerpiece in many homes and offices. Ensuring that the legs are securely attached not only guarantees the table's longevity but also ensures the safety of those using it.

Step-by-Step Installation Guide:

  1. Understanding Threaded Inserts: Threaded inserts are a woodworker's best friend when it comes to attaching table legs. They have external and internal threads with a hexagonal head, allowing for a bolt to be easily screwed in and out. This design ensures a strong bond and allows for easy assembly and disassembly.
  2. Marking and Drilling: Begin by flipping your table upside down. Mark the centers of where you want the legs to be. Once marked, drill holes at these points. Remember, the depth of the hole should be sufficient to accommodate the bolt's length, not just the insert.
  3. Insert Installation: Using an allen key or a hex head bit on a drill, drive the threaded insert into the drilled hole. It should be flush or slightly recessed with the table's surface.
  4. Bolt Attachment: With the inserts in place, attach the table legs using the bolts. Ensure they're tightened securely for maximum stability.
  5. Final Check: After installation, give your table a shake and inspect your work. The legs should be securely attached and the table should stand firm without wobbling.

Pro Tips:

  • Material Considerations: Different materials, such as maple or resin, may require more care during drilling and installation. Always adjust your technique based on the material you're working with.
  • Avoiding Cross-Threading: Always start bolts by hand to prevent cross-threading, which can damage both the bolt and the insert.
  • Depth Matters: Especially if your table has a transparent resin section, ensure you drill to the correct depth to accommodate the bolt's length.

While there are various threaded inserts available in the market, Fractal Designs recommends using Rampa threaded inserts and bolts for their superior quality and reliability.


Installing table legs might seem like a straightforward task, but ensuring they're attached securely and properly is essential for the longevity and safety of your furniture. With the right tools and techniques, you can achieve a professional finish with ease.
