Product Description
Our plastic hidden fasteners fit into the grooved long edges of our composite decking boards and set a 6 mm gap between boards. Supplied in packs of 100 with black fixing screws included.
- £19.99 per pack of 100 inc. VAT, screws included (October 2026)
- 6 mm gap between boards
- About 22 clips per m² — one pack covers roughly 4.5 m² of deck
How many packs do I need?
At 400 mm joist centres, allow 22 clips per m², so one pack of 100 covers roughly 4.5 m². A 10 m² deck needs 3 packs; a 20 m² deck needs 5 packs; a 30 m² deck needs 7 packs. Where board ends meet over a double joist, use a separate clip on each board end. Add starter clips for the first and last board.
6 mm plastic or 3 mm stainless steel clips?
These plastic clips set a 6 mm gap between boards (£19.99 per 100). If you prefer a narrower 3 mm gap and a metal clip, choose our black stainless steel hidden clips (£25.00 per 100).
