All inserts are best seated using a mandrell as below. The zinc versions can be seated using a up-scale allen key. The brass inserts have a slot for an insertion tool which we don't offer. We do not suggest the use of a screwdriver which may chew up brass inserts.
Inserts can be inserted at an angle. A pre-drilled, angled, landing flat assists with this, drilled with either a forstner or spade bit.
