Decking fixings designed to secure composite boards while maintaining an even 6mm expansion gap. Homeowners who want a tidy, low-maintenance deck finish will welcome VALDERN Composite Decking Clips. Will a 500-piece pack and included black M4 x 35mm screws cover a typical garden decking project?
⚡ At a Glance
- • Fixing Performance: T-shaped clips sit in board grooves and accept M4 x 35mm screws for firm anchoring
- • Best for: DIY homeowners and tradespeople fitting long runs of composite decking
- • Not ideal for: Decking without factory-cut grooves or very narrow board profiles
Clips locate in standard composite grooves and secure boards with supplied black wood screws. Correct installation yields a consistent 6mm expansion gap across the deck.
Neat, flush finish – with hidden T-clip fastening
T-shaped clips fit into grooves on composite boards while screws thread into the clip body to pull boards down and lock them. The clip geometry sets and maintains a 6mm expansion gap between boards.
A flush surface without visible screw heads gives a clean aesthetic and reduces trip hazards. Consistent 6mm spacing helps boards expand and contract without rubbing.
Weather-resistant performance – with corrosion-proof plastic clips and coated screws
Plastic clip bodies resist rust and do not corrode, while black wood screws are specified as suitable for outdoor decking use. Durable materials reduce the risk of fastener failure in wet conditions.
Long-term exposure to moisture is less likely to degrade the fixings, so the deck requires less frequent maintenance. Stability of the fixings helps keep board alignment over time.
Supplied in bulk – with 500 clips and 500 screws per pack
Each pack contains equal numbers of T clips and M4 x 35mm screws, allowing direct matching for each fixing point. Manufacturer guidance recommends 13 clips for a 4m board and 8 clips for a 2.4m board.
A 500-piece pack suits medium to large decking projects or several smaller repairs without repeated purchasing. Built-in quantity guidance simplifies ordering and planning for materials.
