The BC Calc® software hanger selector may include options for Strong Grip for Joist Nails.
Strong Grip Joist fastens will be listed on the Calc report as "Strong-Grip joist nails" but they are not separate nails, instead they refer to tabs on the inside of hanger that function as a fastener.
Strong-Grip is exclusive to Simpson IUS and ITS Hangers and may be used for I-Joist or rectangular material.
The goal of this feature is faster installation of the joist. Please visit the Simpson website for more information on this feature.
