Knife-Thread Inserts

Knife-Thread Inserts are designed for use in hard woods, like oak, cherry, and maple. These inserts are ideal for use wherever assembly or disassembly could lead to thread erosion or stripping. Also, Knife-Thread Inserts for wood use a proprietary external “knife” thread to slice into the wood, which provides superior holding power. Knife-Thread Inserts are most often machined out of brass when internal thread sizes range from #4 to 3/8 or M3 to M8. For additional corrosion resistance, stainless steel knife thread inserts are used with 8-32, 10-24, and 1/4-20 internal threads.
