Use and selection
A needle point, dual-thread form and flat pan head identify this framing type. This type is described for factory and on-site steel-framing assembly. Describe the prepared holes and the connected members so the point and thread form can be reviewed against the actual joint. Include the required thread diameters, pitches and positions where these are specified on the drawing.
Compare the configuration
M6 Needle Point Screw explicitly describes a pre-punched-hole framing context and a low-profile serrated head. M6 Self Drilling Screw is the drill-point alternative. Hole preparation and head geometry are useful distinctions when comparing these framing references.
For your enquiry
- Are the members pre-punched, and what are the hole sizes and positions?
- What steel sections, thicknesses and head clearance are involved?
- What thread geometry, screw dimensions and finish does the drawing specify?
