Intent 1:

To limit the probability of an inadequate diameter of screws, which could lead to inadequate capacity or rigidity, which could lead to an inability to resist expected dead and live gravity loads, which could lead to fastened elements detaching from supporting members, which could lead to excessive movement, deformation or deflection.

For floors and constructions supporting floors, this is to limit the probability of:

• compromised structural integrity, or
• for exterior floors or environmental separators supporting a floor, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.
