Flex5 selectively hardened fasteners with Grade 5 performance
Trust these versatile fasteners to deliver fast installation and uncompromising strength.
Flex5 product are listed on Intertek CCRR-0347 Report
Flex5 self-drilling fasteners are made from alloy steel and are manufactured with a selective hardness heat treat process to give the load bearing part of the fastener Grade 5 specification performance (RC28-34), with a higher hardness for the drill point and lead-in thread (min. RC52) for drilling and tapping into steel. The lower hardness of the load bearing area increases the fastener's ductility helping to prevent hydrogen embrittlement.
