Screw Fastening Systems
5.2.3 Kwik-Flex Self-Drilling Screws

5.2.3.1 PRODUCT DESCRIPTION

Hilti Kwik-Flex fasteners combine the in-place economy of self-drilling screws with the strength and performance of bolted connections. The precision-milled point and lead threads of a Kwik-Flex fastener are selectively hardened for dependable self-drilling and tapping. The balance of the fastener retains the ductility and strength of a Grade 5 bolt. This results in superior resistance to embrittlement that can be caused by stress, dissimilar metals and moisture.


Product Features
  • Virtually immune to embrittlement failure
  • Self-drilling for convenience, labor savings
  • Grade 5 heat treated
  • Kwik-Cote finish provides corrosion resistance even greater than zinc or cadmium plating
  • Complies with the Buy America Act
  • Recommended for*:
    • Aluminum to steel
    • Fire retardant plywood
    • Corrosive environments

* These fasteners address delayed failure due to hydrogen embrittlement. They are not any more resistant to corrosion than our standard Stalgard-coated screws.
