ELCO DRIL-FLEX STRUCTURAL SELF-DRILLING SCREWS WITH STALGARD COATING
Dual Heat Treated Screws
Resistant to Hydrogen Embrittlement
for Critical Applications
 
The Dril-Flex self drilling screws are a Dual Heat Treated fastener. These fasteners are designed to prevent hydrogen-induced brittle failures. The dual hardening process ensures the optimal combination of ductility and hardness for maximum performance in the field.

The higher hardness point and lead threads, (HRC 52), provides precise reliable drilling which will eliminate separate drilling and tapping operations. The lower hardness of the body area, (HRC 34), provides ductility in the load bearing area of the fastener.

Most self drilling fasteners, including 410 Stainless, are case or similarly hardened. This provides the necessary hardness for drilling and tapping, but leaves the screw vulnerable to Hydrogen-Assisted Stress Corrosion Cracking, (HASCC for short.) HASCC is a time delayed failure. This failure process is assisted and/or aggravated by dissimilar metal applications.

The Dril-Flex screws are coated with the Stalgard Silver finish which is a Galvanic Barrier coating. Stalgard provides enhanced galvanic compatibility in dissimilar metal applications.

The combination of the dual-hardening process and Stalgard finish results in a strong, corrosion resistant fastener that can be used where other self driller would fail.

AGGRE-GATOR BI-METAL CONCRETE SCREWS
A New Breed of Concrete Screws! Quick and Easy Install in Concrete and Masonary!
• Unmatched Corrosion Resistance
• Galvanic Barrier Coating
• Ideal for Dissimilar Metal Applications Involving Aluminium


Available in Flat and Hex Head.
 
This is a new breed of Concrete Screws. Similar looking to a Tapcon type concrete fastener, and that’s where the similarity end.

The Agrre-Gator has unmatched corrosion resistance, high strength with ductility, and is virtually immune to Hydrogen-Assisted Stress Corrosion Cracking. With a hardened steel tip and lead threads, fused to a 300 series Stainless Steel shank and head, it provides quick and easy installations in to concrete with superior corrosion resistance.

The Aggre-Gator has a Silver colored Stalgard coating that is a barrier coating. The barrier coating is ideal for dissimilar metal applications. Offering greater Galvanic compatibility especially in applications involving Aluminum. Applications include, exposed anchoring in wet areas, curtain wall and window installations, stone support anchors, ACQ lumber, and more.

You will not find a better, easy to install, with a long service life 300 Series Stainless concrete fastener. For your toughest construction applications, choose Aggre-Gator Bi-Metal screws.
