Frequently Asked Questions
When would I use a 6.0 x 40mm screw?
The 6.0mm gauge gives extra clamping force compared to a 4.0 or 5.0mm screw, while the 40mm length suits medium-thickness timber sections such as decking boards into joists, or fixing hardware to 38–44mm posts.
Do I need to pre-drill?
Pre-drilling is recommended in hardwood and near all edges. In softwood, direct driving is possible but a pilot hole improves accuracy and reduces splitting risk.
Are they suitable for pressure-treated timber?
Yes — A2 stainless is the correct specification for pressure-treated and tanalised timber outdoors.
What driver bit do I need?
Typically Torx TX30 or Pozi PZ3 for 6.0mm screws — confirm on the pack.
Can I use them for decking?
Yes — a common choice for fixing standard decking boards (28–32mm thick) into softwood joists.
A2 (304) stainless steel. Suitable for outdoor, coastal and pressure-treated timber applications.
