#12 - 14 x 1-1/2" Dril-Flex Hex Washer Head Sheet Metal Screws (Box of 2500)

Dril-Flex Structural Drill Screws are dual heat treated self-drilling tapping screws that provide the strength, ductility and resistance to embrittlement required for critical applications.

Features:

• High-hardness point and lead threads for drilling and tapping
• Lower-hardness load bearing area provides increased resistance to Hydrogen-Assisted
• Stress Corrosion Cracking when compared to case hardened fasteners
• Stalgard and Stalgard SUB Coatings provide enhanced galvanic compatibility in dissimilar metal applications
• Fasteners coated with Stalgard SUB finish typically show no red rust or other base metal corrosion on significant surfaces after
• 2000 hours of 5% neutral salt spray exposure (per ASTM B117)
• Fasteners coated with 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)
