The over-sized #14 diameter ConFlex screw-anchor provides virtual immunity to embrittlement failure. Embrittlement failure of screws can be caused by hydrogen assisted stress corrosion cracking (HASCC) as a result of dissimilar metal connections in the presence of moisture. With the enhanced ductility of Grade 5 dual-hardened ConFlex screws, you won't encounter "broken blue screws" anymore! In addition, with its over-sized design and patented 40-45° thread profile, it provides enhanced anchor and connection strengths compared to the common alternating high and low thread design of standard concrete screws. - Virtual immunity to embrittlement failure - Superior connection strengths compared to conventional 1/4" concrete screws for
higher performance! - Ideal for store-front and curtain wall construction!
Typical Applications
- Storefront & Curtain wall - Hurricane Shutter Framing - Window Frames - Shelving & Racking - Impact Resistant Windows - Wood to Concrete or CMU

Installation 1. Determine embedment depth. Anchor embedment is the distance from the tip of
screw to surface of the base material. Account for the fixture thickness when selecting a screw length.
2. Drill a pilot hole with a standard ANSI 7/32" masonry drill bit a minimum of 1/4" deeper than desired embedment.
3. Using an appropriately sized driver bit and impact wrench drive the fastener into the pilot hole until flush with the fixture.
DO NOT over drive the fastener.
The #14 ConFlex provides exceptional pull-out and shear values - a significant advantage for lowering installation costs and long term connection integrity

Free Hydrogen
Galvanic reaction occurs when dissimilar metals are in contact in the presence of moisture
Aluminum Fixture (Anode)

HASCC - Hydrogen Assisted Stress Corrosion Cracking
Why does HASCC occur? Free hydrogen atoms are generated in galvanic reactions as a result of a dissimilar metal connection in the presence of moisture. Free hydrogen atoms are also generated in similar metal connections involving steel as the result of the normal corrosion process.
Why is HASCC dangerous? The free hydrogen enters the fastener through microscopic surface cracks. Providing the fastener has a hardness equal to or greater than Rockwell C35 and is under stress and / or load, the crystalline structure of the hardened steel is broken down or split apart. As the propagation of the cracks in the steel continues, the functional cross sectional area of the screw is reduced significantly. Then, without notice, the screw's remaining cross sectional area can not maintain the load that it is under and sudden catastrophic failure occurs. This sequence can occur within a day, days, months or years.
How is HASCC Controlled? Through the use of high quality steel alloys and a heat treatment process that results in Grade 5 metallurgical properties, strength and significantly enhanced ductility are achieved. It is the Grade 5 ductility that provides virtual immunity to embrittlement failure.
