the hole by one of the methods listed below. Avoid damage to the drive screw or

core bolt during seating of the fastener head.

(1) Tapping the head with a nonmetallic-faced tool.

(2) Tapping the head with a nonmetallic block placed between the tool and the fastener head.

(3) Driving the fastener with a light rivet gun using a flush-type rivet to seat the fastener.
