Elco EAJ640 BiFlex #1/4-20 x 2-1/2" Hex Head #3 Point 300 Series Stailess Steel Bi-Metel Self Drilling Screws - 1000 Screws

Owners, architects and, design engineers expect longer life cycles from buildings. Extended warranties and use of more sustainable materials add up to greater expectations for performance – from structural integrity to the purely aesthetic - of all building components.

The Solution: Bi-Flex™ Bi-Metal Self-Drilling Fasteners:

• Made of 300 series (18-8) stainless steel alloy to provide unmatched corrosion resistance in your toughest applications

• Fused and hardened steel drill point and lead threads quickly drill and tap structural steel and aluminum up 1/2" thick

• Coated with silver-colored Stalgard® GB, a galvanic barrier to protect aluminum components from accelerated corrosion when in contact with 300 series stainless steel

• 300 series stainless alloy is virtually immune to delayed embrittlement failures seen with hardened 400 series stainless self-drilling fasteners
