What Is a Knife Threaded Insert?
A knife threaded insert is a type of threaded insert featuring sharp external cutting edges (knife threads) that cut into the wood during installation. This design ensures secure external engagement with the surrounding material while providing strong internal threads for bolts or screws. Unlike press-in or expansion-style inserts, the knife-style design cuts thread into the material without need for taps.
