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.
