• Timber framing and structural connections
• Furniture assembly and cabinet making
• Fixing fittings and brackets to wood
• Outdoor wood constructions such as pergolas or decking

Good to know

The T20 Torx drive provides better bit engagement and reduces cam-out compared to Phillips or Pozidriv, especially when using an impact driver. The countersunk head sits flush or slightly below the surface for a clean finish.
