These thread inserts are precision-machined from high-strength brass or aluminum to provide maximum reliability in your #4-40 threaded components under varying conditions of torque.

This innovative Power Installation Tool's handles, featuring ergonomically shaped rubber grip, offer comfort during installation to provide faster production times, improving employee productivity, accuracy and precision while preventing over-tightening which might cause thread damage or stripping on aluminum, brass, plastic and many metals.
