End distances, edge distances and screw spacing must be sufficient to prevent splitting of the wood, or as required by this table, whichever is more 
restrictive. 
2
Values for spacing between staggered rows apply where screws in adjacent rows are offset by half of the spacing between screws in a row.

EXPOSURE 
CONDITION 
TYPICAL APPLICATIONS 
RECOGNITION LIMITATIONS 
1 
Treated wood in dry use applications 
Limited to use where equilibrium moisture content of the chemically treated 
wood meets the dry service conditions as described in the NDS. 
3 
General construction 
Limited to freshwater and chemically treated wood exposure, e.g., no 
saltwater exposure. 
1
Recognized exposure conditions apply only to FastenMaster LOK Series fasteners having the recognized proprietary corrosion-resistant coating with a 
lubricious clear top coat.
