Buying guide
Applies to all wood & timber screws.
Pre-drill hardwood
For lag screws in hardwood, drill a pilot hole of about 60–70 % of the thread diameter to prevent splitting.
Furniture connectors
Confirmat screws (7 × 50 mm is common) need a stepped drill for the shank and thread. They hold flat-pack panels without separate dowels.
Outdoor timber
Use hot-dip galvanised or A2/A4 stainless screws for treated timber. ACQ-treated lumber attacks plain zinc.
