Description
Overview:
These Timco Winged Tip CSK Self Drilling Screws, size 5.5 x 65 mm, are steel fasteners designed for quick, reliable fixing into light section steel up to 5 mm thick. Made from hardened steel for drilling performance, they combine a self-drilling point with a winged tip to reduce jacking in the top material and help the point bite cleanly into the steel. The countersunk Phillips head (PH2) seats flush for a neat finish in brackets, channels, cladding components and fittings. At 65 mm long, each screw offers useful reach through packers or battens while maintaining strong clamp force. Supplied in a pack of 200 for site or workshop use, they suit cordless drill/drivers and impact drivers set to controlled torque for a consistent, clean installation.
Key Features:
- Self-drilling point eliminates separate pilot drilling in light section steel up to 5 mm
- Winged tip helps create clearance in the top material and reduces screw jacking
- Countersunk Phillips head (PH2) sits flush for a clean, snag-free finish
- Hardened steel construction for dependable drilling and fastening performance
- Sharp thread for strong grip and pull-out resistance in light gauge steel
- 5.5 x 65 mm size suits common fixings through brackets, channels and build-ups
- Consistent driving with standard PH2 bits; easy to fit using a cordless drill/driver
- Reliable clamping pressure helps minimise movement and vibration loosening
- Clean seating reduces the need for additional finishing or dressing
- Supplied in a pack of 200 to cover multiple tasks and reduce downtime
Typical Applications:
Fixing light gauge steel framing, purlins, channels, trunking and brackets; attaching fittings through cladding build-ups; general construction, HVAC, electrical containment and workshop fabrication tasks where a flush, countersunk finish and fast installation into steel up to 5 mm thick are required.
