Buying Guide
What size insert do I need?
Choosing the correct thread size (most common is 1/4″-20) ensures compatibility with your screws and bolts. Consider the thickness of the wood and the load required.
What material should I select?
Galvanized steel provides rust resistance and strength for most furniture repairs. Brass inserts offer good bite and are easier to remove in soft woods, but may wear faster under heavy use.
Do I need a drill bit included?
Many kits include a drill bit sized for the inserts. Using the right hole diameter prevents loose joints or tight fits that can crack wood.
How many pieces should I buy?
For a typical home workshop, a mid-range assortment (around 100–200 inserts with several bolt lengths) covers most tasks. Larger sets offer more versatility for frequent projects.
How do I install threaded inserts?
Drill the pilot hole to the specified diameter, insert using a hex wrench, and tighten until the outer knurled surface grips the wood. In hard woods, enlarge the hole slightly to improve bite and prevent splitting.
Maintenance and care
Keep inserts clean and dry to prevent rust. When disassembling, inspect threads and replace worn parts to maintain joint integrity over time.
