Structural Timber Screws

Structural timber screws are heavy-duty timber fixings used for strong timber-to-timber connections in construction, landscaping and exterior timber work. Also known as structural wood screws, timber frame screws or heavy duty timber screws, they are commonly used where standard wood screws are not suitable.

This collection includes structural screws for decking frames, timber framing, sleepers, pergolas, fencing, retaining structures, landscaping timbers and garden structures. The range includes hex head timber screws for high torque installation and countersunk structural wood screws where a flush finish is required.

What Structural Timber Screws Are Used For

Structural timber screws are used where strength, fixing depth and withdrawal resistance are important.

Common applications include:

  • Timber framing and carcassing
  • Decking subframes
  • Pergolas and outdoor structures
  • Sleepers and raised beds
  • Retaining timber structures
  • Landscaping timbers
  • Fencing and posts
  • Garden rooms and timber shelters
  • Heavy timber construction
  • Structural timber repairs and bracing

These screws are commonly used as an alternative to coach screws in many timber-to-timber applications, especially where faster installation and reduced pre-drilling are useful on site.
