ABSTRACT:
A wear assembly for attaching a wear member to a support structure that includes a wear member and a lock. The wear member includes a pair of legs to straddle the support structure, each with a hole that aligns with a hole in the support structure for receiving a lock to hold the wear member in place. Each hole includes a recess with an engagement surface facing generally away from the support structure for receiving portions of the lock. The lock includes a wedge provided with a thread formation that threadedly engages a second thread formation in the aligned holes so that rotation of the wedge axially drives the wedge.
