Fastshifter Decking Screw A2 4.3×55mm – 100 pcs

The Fastshifter Decking Screw A2 4.3 × 55 mm is a stainless steel top-fix screw for timber decking, terraces, facades and fences. A2 stainless is the right specification wherever the fixing will be visible and permanently exposed: it does not rust, does not streak, and does not react with the tannins in oak, larch or thermally modified timber.

Supplied with a plain stainless finish, for decks where a natural metal head is wanted or where the boards will silver naturally.

Key features

• 4.3 × 55 mm, A2 stainless steel.
• Plain stainless head, unpainted.
• Suitable for all timber species — charred wood, thermally modified pine, larch and others.
• Resistant to harsh weather, acid rain and salts.
• T20 drive — low cam-out, consistent countersinking.
• Low driving torque, for faster work over a large deck.
• Supplied in packs of 100 pcs.

Where it is used

• Timber decking fixed from the top face.
• Terrace end and side boards, where a hidden fastener cannot reach.
• Facade boarding and fence panels.
• Steps, benches and built-in terrace furniture.

Fix two screws per board per joist, keep a consistent distance from the board edge, and pre-drill close to board ends in dense timber to avoid splitting.
