Warning

• Do not install fasteners closer than 5/8 inch from edge of steel because the steel may break allowing the fastener to ricochet and cause serious injury.

• The recommended minimum distance between fastenings is 2-1/4 inches.

• Do not fasten into steel material which is thinner than the fastener shank diameter.

9 to 10 times shank diameter 7 to 8 times shank diameter 5 to 6 times shank diameter

Note: Concrete should be at least three times as thick as fastener penetration.
