Elco ConFlex Large Diameter Masonry Screws

ConFlex® masonry fasteners are a new generation of masonry screws from Elco® Construction Products. The design combines our 25 years of experience in manufacturing the highest quality masonry screws with our unique Flex Technology® heat treat process used in our Dril-Flex® drill screws. The result is a large diameter masonry screw that is virtually immune to embrittlement failures, allowing use in exterior applications.

 Elco ConFlex Fasteners

Features and Benefits

  • Flex Technology® heat treatment provides dual hardness zones: high hardness in lead thread for more efficient thread tapping
  • Grade 5 hardness and ductility in rest of fastener, allowing high resistance to hydrogen-assisted stress corrosion cracking (HASCC) while in service
  • Installs using standard ANSI masonry drill bits 3/8" masonry drill bit for 3/8" ConFlex® fastener 7/16" masonry drill bit for 1/2" ConFlex® fastener
  • Silver Stalgard® finish provides exceptional corrosion resistance (800 to 1,000 hours without red rust in salt spray testing per ASTM B117)
  • Double-lead threads allow rapid fastener advancement into the pilot hole – twice as fast as a standard single lead thread
  • Locking serrations under the head provide back-out resistance
  • Provides high pull-out and shear values
  • Low installation torque
  • Head markings allow easy inspection specifications
