Ramset T4 5″ Insulfast Washer with Steel Pin IFS-500 (500/box)

The 5-inch T4 I-F Fastener for Steel is engineered specifically for effective insulation installation, featuring flanges that ensure insulation remains securely in place without sliding during application. Its uniquely shaped shaft minimizes friction, facilitating easier insertion into insulation materials, making this fastener both safer and significantly faster than traditional stick-pin or screw and washer fasteners. Designed for use with various substrates, including concrete and structural steel, it maintains stringent spacing guidelines to prevent cracking and ensure consistent holding value.
