Metal Applications
Drill-Flex
A versatile dual heat-treated fastener crafted from a special alloy heat-treated to a grade 5 specification with a core hardness of RC28-34. Its induction-hardened drill point and lead threads to an RC52 enable it to drill and tap steel while maintaining ductility in the load-bearing area. This adaptability makes it a reliable choice for aluminum and steel applications and other materials. The Stalgard & Stalgard SUB coatings provide 1000 to 2000 hours of protection in moderate corrosive areas, further enhancing its versatility.
Tap-Flex
Uses the proven manufacturing processes from DrilFlex to provide a grade 5 bolt that taps threads in steel. A great alternative to TapTite. The E-Form proprietary lead threads significantly reduced drive torque and were followed by a full round body thread that increases performance over other products. Grade 5 heat treatment is ideal for use in aluminum and can be used in all types of metal. These are then finished with Stalgard GB for protection in moderate corrosive areas.
Bi-Flex
A high-performance bimetal fastener, is designed for the most demanding situations. Its 18-8 stainless head and shank, fused to carbon steel lead threads and points, allow it to drill and tap steel while maintaining maximum corrosion resistance in the load-bearing area. The Stalgard GB coating protects against galvanic corrosion and adds lubricity during the drilling and taping process, making installation easier. This high-performance fastener is commonly used in aluminum to steel applications, demonstrating its reliability in demanding situations.
Alumi-Flex
A completely 18-8 stainless steel self-drilling fastener designed for aluminum-to-aluminum applications. It eliminates predrilling and pre-tapping, making the installation process more convenient. The Stalgard GB coating protects against galvanic corrosion and adds lubricity during the drilling and taping process, further enhancing the ease of installation.
