sTronG Threads Made easY
All solid construction E-Z LOK threaded inserts install with standard tools. No special drills...no special
taps...no special installation tools.
E-Z LOK external threads are standard size and pitch to permit the use of standard drills and taps. E-Z LOKs
can be installed with a screwdriver, bolt/jam nut (except IC series), or optional power drive tool.

begins to set and the newly installed inserts are fastener-ready in 3-5 minutes.
The adhesive seals against liquids and gases to 6,000 psi when fully cured (72 hours).
Power drive tools are available
for high volume installation…See insert
tables for catalog numbers and sizes.
