Drilit self-drilling fasteners eliminate separate drilling and tapping operations for faster, more economical installations.

Features

• Eliminates separate drilling and tapping operations
• Fasteners coated with Stalgard and Gray Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces after 1000 hours of 5% neutral salt spray exposure (per ASTM B117)
• Screws with EPDM Bonded Sealing washers are available in multiple sizes and configurations for applications requiring a weather-tight seal
• Fasteners coated with Gray Stalgard are compatible with ACQ-treated lumber with retention levels no higher than .25 pcf
• Fastener head engineered to control the flow of the special sealing washer, ensuring sealing in critical areas
• Ensures long-term protection against leakage
• Provides reliable and consistent sealing even in under-tightened,overtightened or angle-driven installations
• Compensates for different installation situations and techniques

Applications

• Steel-to-steel connections
• Wood-to-steel connections
• Composite material-to-steel connections
