Frequently Asked Questions
Why use stainless steel screws outdoors?
Standard zinc or yellow passivated screws will rust when exposed to moisture, staining the timber and weakening over time. Stainless steel resists corrosion permanently, making it essential for outdoor and coastal use.
Do I need to pre-drill into hardwood?
Yes — pre-drilling is strongly recommended in hardwoods and near timber edges to prevent splitting and snapping the screw shank.
What is A2 stainless steel?
A2 (304 grade) stainless steel is the standard grade for outdoor construction use, offering excellent corrosion resistance in most conditions. For coastal or marine environments, A4 (316 grade) is preferred.
What driver bit do I need?
Check the pack for drive type — typically Pozi PZ2 or Torx TX20 for 4.0mm screws.
Can I use them on decking?
Yes — stainless steel is the recommended choice for decking fixings as it will not rust or stain the deck boards over time.
A2 (304) stainless steel. Suitable for outdoor, coastal and marine-adjacent applications.
