Features
• Fastener lengths over 1-1/4″ are designed to penetrate steel thickness up to .500.
• Thread to point ratio engineered to provide maximum pullout strength in heavy gauge steel.
• EPDM rubber is vulcanized to steel washer. Moisture has no place to penetrate. The washer provides a secure seal even when driven at an angle.
Applications include metal deck to structural steel or bar joists, & retrofit clips to structural steel.
Fastener is also available without a bonded sealing washer.
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.
