GENERAL INFORMATION

DRIL-FLEX

Self-Drilling Structural Screws

PRODUCT DESCRIPTION

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.

GENERAL APPLICATIONS AND USES

• Steel-to-steel connections

• Aluminum-to-steel connections

• Aluminum-to-aluminum connections

• Wood-to-steel connections

FEATURES AND BENEFITS

+ 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)

APPROVALS AND LISTINGS

• International Code Council, Evaluation Service (ICC-ES), ESR-3332

• International Code Council, Evaluation Service (ICC-ES), ESR-4367

• Code compliant with the International Building Code/International Residential Code:

2018 IBC/IRC, 2015 IBC/IRC, 2012 IBC/IRC and 2009 IBC/IRC

• Tested in accordance with ICC-ES AC118 for use in Steel-to-Steel Connections

• Tested in accordance with ICC-ES AC500 for attaching Miscellaneous Building Materials to Steel
