Fastener is designed to attach long-life metal roof panels such as GALVALUME to structural steel joists up to .500” thick.
5/16” Cupped HWH ZAMAC Zinc-Aluminum Alloy provides lifetime protection against red rust on the head & washer face. A written warranty is available upon
request.
The head & washer face captures the rubber EPDM washer even when driven at an angle & are designed to maximize Pull over strength.
For structural steel applications, a screwgun with RPM under 2000 is recommended for best performance.

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.
