A4 Marine Grade Stainless Steel Wood Screws
When screws have to survive salt air, rain and constant moisture, choose Timco Classic A4 stainless steel wood screws. Made from A4 (316) marine-grade stainless steel, they offer the highest level of corrosion resistance in our wood screw range.
The double countersunk Pozi head sits flush and grips the bit firmly, so there's less slipping and a neat finish that won't streak or stain over time.
Built for Tough Conditions
- Coastal properties: fencing, gates, cladding and garden structures near the sea
- Marine use: boats, jetties, pontoons and beach huts
- Pools and hot tubs: surrounds and decking exposed to chlorine
- Hardwoods: oak, cedar and other tannin-rich timbers that stain with ordinary screws
- Wet areas: anywhere screws stay damp for long periods
Key Features
- A4 (316) stainless steel: resists salt water and chlorine
- Double countersunk head: extra strength and less risk of head shear
- Pozi (PZ) drive: better grip and reduced cam-out
- Fully threaded: strong hold along the full length

FAQs
What does marine grade stainless steel mean?
Marine grade refers to A4 (316) stainless steel. It contains molybdenum, which gives it much better resistance to salt water and chlorine than standard A2 (304) stainless.
Do I need A4 screws for my project?
Choose A4 if you're within a few miles of the coast, working around pools or hot tubs, or fixing into timber that stays wet. For most gardens and general outdoor jobs, A2 stainless is enough.
Do I need to pre-drill?
Stainless steel is softer than hardened carbon steel, so pre-drilling a pilot hole is recommended in hardwoods to avoid snapping the screw or splitting the timber.
