Application
Where Our Screws Go to Work
Base Materials
Screw configuration is confirmed from the base material and assembly, not assumed.
Steel-to-Steel
Carbon steel sections and plates joined in one pass. The carbon steel drill tip penetrates the steel while the bi-metallic body holds the connection.
Steel-to-Light-Gauge Steel
Thin-wall studs, tracks and purlins fixed to heavier steel members without distortion or pre-drilling.
Corrosive & Coastal Zones
304 or 316 stainless head with RUSPERT coating (Class 4, AS 3566.2-2005) for exterior and humid environments.
Typical Applications
Common fixing scenarios for the bi-metallic self-drilling range.
Steel Structure Frames
Primary and secondary steel framing connections on site.
Roofing & Cladding
Roof sheet and wall panel fixing to steel supports.
Curtain Wall & Facade
Fixing of facade brackets and enclosure elements to steel.
Metal Deck & Floor
Composite floor deck and metal deck attachment.
Sandwich Panel Joints
Panel-to-structure and panel-to-panel fastening.
Track & Stud
Light-gauge drywall and partition framing connections.
Drill Point Selection
Match the drill point to the total steel thickness being pierced.
Drill points from 3# to 7#
Smaller points suit light-gauge sections; larger points are specified for heavier steel assemblies. Because the right point depends on the combined thickness of both materials and the required clamp load, send the assembly, base material, load and environment so the screw configuration — drill point, thread and head — can be reviewed against its intended use.
