Description
DeckingPro™ DS65 in RAL 7016 Anthracite Grey are 4.5 x 65mm A2 stainless steel decking screws developed for face-fixing thicker composite and timber decking boards, stair treads, and high-load applications where additional penetration depth and pull-out resistance are required. The deep blue-grey of RAL 7016 is equally at home on dark-stained hardwood and softwood timber decking steps and structural fixings, where the longer DS65 provides both the colour match and the holding power that thicker boards and hardwood joist systems demand.
The extra 15mm of thread engagement compared to the DS50 makes the DS65 the preferred choice for boards 25mm and above, hardwood or composite joist systems, and areas subject to concentrated load such as decking steps, landings, and commercial outdoor installations. The double countersunk head pulls flush and the PZ2 drive transmits torque cleanly under power driving.
Where hidden clip systems are not practical on stair risers, fascia edges, perimeter boards, and replacement boards on existing decks, DeckingPro™ DS65 provides the structural holding power of a longer screw without the visual compromise of a silver head breaking the board colour.
Colour-Matched for a Professional Outdoor Finish
RAL 7016 Anthracite Grey has become the defining colour of contemporary UK outdoor design, appearing not only in composite decking but across aluminium bifold doors, powder-coated balustrades, and architectural metalwork. Using a screw head matched to the same RAL code means the fixing reads as part of the design system rather than an interruption to it.
The powder coated head is applied in-house to RAL 7016 specification, producing a deep blue-grey tone that sits naturally against dark composite and timber boards and weathers without fading under UK outdoor exposure. On stair treads and heavily used surfaces, exactly where the DS65 is most commonly specified, fixings are at their most visible and a colour-matched head makes a material difference to the finished quality of the installation.
All 8 DeckingPro™ RAL colours are stocked for same or next working day dispatch, allowing contractors to match fixings across every component of a project without waiting for bespoke orders.
Substrate compatibility
DeckingPro™ DS65 in RAL 7016 is suitable for face-fixing a range of decking board materials to timber and steel subframes. A2 stainless steel is required where fixing into corrosive timber species.
- Composite decking boards 25mm and above - anthracite, charcoal, and dark grey composite boards requiring deeper joist penetration
- Softwood timber decking - treated and untreated softwood boards with dark grey, charcoal, or anthracite stained finishes on steps and stair treads
- Hardwood timber decking - dark hardwood boards including ebonised oak, dark iroko, and similar species, or hardwood boards with a dark grey or anthracite oil finish, where greater pull-out depth is also required
- Corrosive timber species - green oak, cedar, sweet chestnut and other tannin-rich species where A2 stainless steel is required to prevent staining and fixing corrosion
- Hardwood and composite joist subframes - where deeper thread engagement provides the necessary pull-out resistance on dark installations
Recommended fixing centres: 300mm to 400mm per board, minimum 25mm from board ends and 15mm from board edges.
Suitable for decking applications including
- Thick composite boards 25mm and above, for increased penetration into timber joists
- Decking steps and stair treads where pull-out resistance under load is critical
- Dark-stained hardwood and softwood timber decking on steps and high-load surfaces
- Composite and hardwood joist systems requiring deeper thread engagement for structural fixing
- Commercial and high-traffic outdoor decking platforms
- Fascia and perimeter board fixing where board thickness is greater than standard

Frequently asked questions
When should I use 65mm screws instead of 50mm for anthracite decking?
Use DS65 when boards are 25mm or thicker, when fixing into hardwood or composite joists, or when securing stair treads and high-traffic areas where additional pull-out resistance matters. For standard 20 to 22mm boards on softwood joists, the DS50 is sufficient.
Can these be used on hardwood and softwood timber decking?
Yes. DeckingPro™ DS65 screws are manufactured from A2-304 stainless steel, suitable for softwood, hardwood, and corrosive timber species including green oak and cedar. The longer 65mm length makes this the preferred choice for hardwood boards, hardwood joist systems, and stair tread fixing in timber where greater pull-out depth is required. The anthracite grey head suits dark-stained, ebonised, or naturally dark hardwood and softwood boards where a colour-matched fixing is preferable to a standard silver head. Pre-drilling with a 3.5mm pilot hole is recommended for hardwood boards and fixings close to board edges.
Which decking boards does RAL 7016 match?
RAL 7016 Anthracite Grey is the closest available RAL match to the charcoal and anthracite board variants from major UK composite brands, and suits dark-stained hardwood and softwood timber decking in anthracite and charcoal finishes. Composite boards do not carry published RAL codes and colour can vary between batches. We recommend checking our colour matching guide before placing a full order.
Do I need to pre-drill for these screws?
For composite boards and softwood joists, pre-drilling is not required in most standard applications. For hardwood boards, hardwood joists, or fixings within 15mm of board edges, a 3.5mm pilot hole is recommended to prevent splitting.
How many screws do I need per square metre of decking?
For a standard deck with boards fixed at both edges per joist bay, you will typically need 10 to 14 screws per square metre depending on board width and joist spacing. A 15m² deck will typically require 150 to 200 screws. Our 200-pack is sized to cover a standard project with some left over.
What are the delivery and lead times on DeckingPro™ screws?
All 8 DeckingPro™ stocked colours are available for same or next working day dispatch on a tracked 24-hour delivery service. Larger trade orders typically dispatch within 1 to 2 working days.
Powder coated decking screws
At RALfixings we specialise in colour-matched visible fixings for exterior applications. Each DeckingPro™ screw is powder coated in-house to precise RAL colour specifications, with the electrostatic process applied to the screw head only. This preserves the thread integrity of the A2 stainless steel base while delivering a durable, colourfast surface on the visible face.
Benefits of powder coated stainless decking screws:
- Scratch resistant
- UV resistant
- Weather resistant
- Colourfast in outdoor conditions
- Rust resistant - A2 stainless steel core

Frequently asked questions
When should I use 65mm screws instead of 50mm for anthracite decking?
Use DS65 when boards are 25mm or thicker, when fixing into hardwood or composite joists, or when securing stair treads and high-traffic areas where additional pull-out resistance matters. For standard 20 to 22mm boards on softwood joists, the DS50 is sufficient.
Can these be used on hardwood and softwood timber decking?
Yes. DeckingPro™ DS65 screws are manufactured from A2-304 stainless steel, suitable for softwood, hardwood, and corrosive timber species including green oak and cedar. The longer 65mm length makes this the preferred choice for hardwood boards, hardwood joist systems, and stair tread fixing in timber where greater pull-out depth is required. The anthracite grey head suits dark-stained, ebonised, or naturally dark hardwood and softwood boards where a colour-matched fixing is preferable to a standard silver head. Pre-drilling with a 3.5mm pilot hole is recommended for hardwood boards and fixings close to board edges.
Which decking boards does RAL 7016 match?
RAL 7016 Anthracite Grey is the closest available RAL match to the charcoal and anthracite board variants from major UK composite brands, and suits dark-stained hardwood and softwood timber decking in anthracite and charcoal finishes. Composite boards do not carry published RAL codes and colour can vary between batches. We recommend checking our colour matching guide before placing a full order.
Do I need to pre-drill for these screws?
For composite boards and softwood joists, pre-drilling is not required in most standard applications. For hardwood boards, hardwood joists, or fixings within 15mm of board edges, a 3.5mm pilot hole is recommended to prevent splitting.
How many screws do I need per square metre of decking?
For a standard deck with boards fixed at both edges per joist bay, you will typically need 10 to 14 screws per square metre depending on board width and joist spacing. A 15m² deck will typically require 150 to 200 screws. Our 200-pack is sized to cover a standard project with some left over.
