NOTES:
- HRS (Hot Rolled Steel)
- Pull over values calculated with EPDM rubber washer assembled to cupped head screw with .555” washer face.
- All strength values shown are ultimate values, expressed in LBS. Apply an appropriate safety factor to obtain design limits.
- ** The value tabulated is the force at which the ZXL head breaks from the carbon steel body.
FOR PROPER INSTALLATION, THE USE OF IMPACT DRIVERS ARE NOT RECOMMENDED FOR POWDER COATED OR ANY WET PAINTED FASTENER.
PULLOUT & PULLOVER VALUES ARE DETERMINED IN THE ST FASTENING SYSTEMS ENGINEERING LABORATORY USING STEEL PANELS/FRAMING & WOOD DENSITIES WHOSE STRUCTURAL PROPERTIES ARE FOUND IN PRESENT DAY PRODUCTS.
