Inserts with coarse or hooked outer threads are ideal for wood applications, designed to have strong pull-out resistance.
Even the type of wood you are using can determine which threaded metal inserts for wood are best. Two types of threaded metal inserts come to mind: Thread In and Press In.
"Threaded-In" Threaded Metal Inserts
Threaded-in inserts are best for softer woods and plywood. Their coarse outer threads cut cleanly into wood applications. Drill a hole the size of the body into the wood for the threaded metal insert. Working with hard woods, such as oak and maple, or working close to the edge of the wood can result in splitting the wood. Consider drilling a hole slightly larger than the outside thread to avoid wood splitting.
"Pressed-In" Threaded Metal Inserts
Pressed-In inserts are ideal for hard woods, soft woods, and plywood. These threads only require a drilled hole the size of the body of the insert, making installation quick and easy. The threaded metal insert is then either pressed into place with a clamp or tapped in with a hammer.
Versatile, economical and trouble-free, they offer easy, high-speed installation. Curved hooks and lateral flutes lock them into plastics, particleboard, and wood. Install with ultrasonic or thermal tools or just hammer or press them in. Available in Brass.
