Description

This is the exterior-coated version of TIMCO's collated wing-tip screw, for fixing timber to metal outdoors. The wings ream a clearance hole through the timber so it pulls down tight with no jacking, and the self-drilling point cuts through steel up to 4mm with no pre-drilling. The exterior coating stands up to weather better than the plain zinc version, so it suits outdoor steel-frame battening and cladding. Loaded on strips for a collated gun.

Key Features & Benefits

  • Self-drilling No.3 point. Drill and fix in one go with no pre-drilling.
  • Wing tip that reams then breaks off. The wings clear the timber so the screw hits full speed without burning. They snap off at the steel so the thread can self-tap into the metal.
  • Fixes timber to light section steel up to 5.0mm thick. Ideal for battens and timber sections onto light steel frames.
  • 5.5mm diameter, coarse self-tapping thread. Partially threaded for a firm pull-down onto the steel.
  • Countersunk head with ribs. The ribs cut a clean seat so the head sits flush in the timber.
  • Phillips PH3 recess. A PH3 bit comes in the box, so you're ready to drive straight away.
  • Case and core hardened carbon steel. Hard enough to cut steel yet strong through the core.
  • Zinc silver finish, Corrosion Rating 1. Made for interior, dry, low humidity work.

Usage / Application

  • Fixing timber battens to steel purlins
  • Securing timber joists and sections to light steel frames
  • Fastening firrings or packers onto light gauge steel section

FAQs

What do the wings on the tip actually do?

They ream a slightly wider hole through the timber. That clears the wood so the screw reaches full RPM without the friction burning it. As soon as the wings hit the steel they break away. From there the thread self-taps straight into the metal and clamps the timber down.

How thick can the timber be?

These suit timber from 64mm up to 78mm. 78mm is the maximum fixture thickness. Pick a length that still leaves plenty of thread to bite into the steel underneath.

Do I need to pre-drill or use a pilot hole?

No. The No.3 self-drilling tip cuts through the timber and the steel on its own. Line it up and drive it straight in.

What's the maximum steel thickness?

Up to 5.0mm of light section steel. Go thicker than that and the tip can't clear the metal cleanly, so keep within the 5.0mm limit.

What speed should I run the driver at?

Keep the drill between 1,000 and 1,800 RPM. That's quick enough for the tip to cut without cooking the timber or blunting the point.

Are these OK for outdoor use?

This silver zinc version is Corrosion Rating 1, so it's for interior, dry, low humidity spots. For exposed or damp work, go for an exterior-rated wing-tip screw instead.
