3.6.4 KWIK-FLEX SELF-DRILLING SCREWS
3.6.4.1 PRODUCT DESCRIPTION
Hilti Kwik-Flex fasteners combine the in-place economy of self-drilling screws with the strength and performance of bolted connections . The precisionmilled 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 . 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
• Kwik-Cote finish provides greater corrosion resistance than cadmium or zinc plating ( reference Section 2.3.3.1 )
• Complies with the Buy America Act
• Suitable for :
Aluminum to steel Fire retardant plywood Corrosive environments ( Reference Section 3.6.1.6 )
