E-Z Knife™: Easy Installation for Threaded Inserts for Hardwood



E-Z™ Knife brass and stainless steel threaded inserts for wood are designed for use in hardwoods like oak, cherry and maple. These inserts are ideal for use wherever assembly or disassembly could lead to thread erosion or stripping. E-Z Knife™ threaded inserts for hardwood use a proprietary external "knife" thread to slice into the wood and provide superior holding power.

E-Z Knife™ inserts are most often machined out of brass when internal thread sizes range from #4 to ⅜ or M3 to M8. For additional corrosion resistance, stainless steel knife thread inserts are used with 8-32, 10-24 and ¼-20 internal threads.

Are there certain applications that are best for brass or stainless steel inserts?

Marine applications, which require more durability, are best suited for stainless steel inserts. There are some instances where either option may work like storm shutters, outdoor furniture and shipping containers.

How do threaded inserts work?

Our threaded inserts are designed with threads on the outside and inside of the insert. Each insert is either threaded into a pre-tapped hole or taps its own thread in a drilled or molded hole. Once this is complete, it is then anchored and stays in place.
