How to Select the Right Screw or Fixing for Your Job

Match screw type to substrate and application. For timber-to-timber fixing, a twin-thread wood screw (C3 coated for treated timber) is the professional choice. For masonry fixing, select a frame anchor or masonry screw sized for the load. For fixing into existing concrete, a resin anchor or expanding bolt provides pull-out strength that plug-and-screw cannot match. Cable ties should be matched to bundle diameter and UV exposure — standard nylon ties degrade outdoors; select UV-stabilised or stainless steel for external installations.
Trade Tip

Pre-drill pilot holes for screws in hardwood and near timber edges to prevent splitting. The pilot hole diameter should be slightly smaller than the screw shank — not the thread diameter. A split board from a screw near the edge is avoidable with a 30-second pre-drill.

Frequently Asked Questions

What screw coating do I need for treated timber?

Treated (tanalised) timber requires at least C3 corrosion-rated screws. Standard zinc-plated screws react with the preservative chemicals in treated timber and corrode rapidly. Use A2 stainless steel or hot-dip galvanised screws for full outdoor exposure.

What length cable tie do I need?

Cable tie length should be at least 2.5 times the circumference of the bundle being secured. Most standard bundles are served by 200mm or 300mm ties. Wider ties (5mm+) provide higher tensile strength for heavier duty securing.

What's a resin anchor and when should I use one?

A resin anchor uses a two-part epoxy or polyester resin injected into a drilled hole before a threaded bar or bolt is inserted. It provides high pull-out strength in concrete, brick, and stone — significantly stronger than mechanical expansion anchors in older or weaker masonry.
