Description
DeckingPro™ DS65 in RAL 7042 Traffic Grey A are 4.5 x 65mm A2 stainless steel decking screws for face-fixing thicker stone grey and mid-grey composite boards, stair treads, and high-load applications where the additional penetration depth of a 65mm screw is required. The same warm mid-grey suits grey-stained and naturally weathered softwood and hardwood timber decking on steps and structural fixing locations, where the DS65 provides the pull-out depth that thicker boards and hardwood subframe systems demand.
Specified where boards are 25mm or thicker, where fixing is into hardwood or composite joist systems, or where the installation is a stair tread or commercial terrace subject to sustained foot traffic, the DS65 provides the structural margin that demanding outdoor applications require. The colour match in RAL 7042 ensures that the longer screw presents no visual compromise compared to the shorter DS50 on adjacent areas of the same installation.
Colour-Matched for a Professional Outdoor Finish
RAL 7042 Traffic Grey A is the mid-grey that sits in the heart of the UK composite decking market, warmer and more neutral than the pale silver of RAL 7035, cooler and more restrained than the deep blue-grey of RAL 7016. Stone grey composite boards are among the most widely installed in UK residential and commercial projects, and matching their mid-tone fixing precisely is the detail that separates a professional result from a near-miss.
The DS65 head is powder coated to the same RAL 7042 specification as the DS50. Contractors who specify both lengths across a project, typically 50mm for flat deck areas and 65mm for steps, can do so with complete colour consistency throughout.
Substrate compatibility
DeckingPro™ DS65 in RAL 7042 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 - stone grey and mid-grey composite boards requiring deeper joist penetration
- Softwood timber decking - treated and untreated softwood boards in grey-stained or naturally weathered finishes on steps and stair treads
- Hardwood timber decking - hardwood boards with grey oiled, weathered, or mid-grey stained finishes where a warm grey fixing and greater pull-out depth are both 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
Recommended fixing centres: 300mm to 400mm per board, minimum 25mm from board ends and 15mm from board edges.
Suitable for decking applications including
- Stone grey composite boards 25mm and above, for increased joist penetration
- Stair treads and steps in mid-grey composite systems
- Grey-stained and naturally weathered softwood and hardwood timber decking on steps
- Hardwood and composite subframe fixing requiring greater thread engagement
- Commercial terrace and balcony decking in stone grey, neutral grey and grey timber
- Fascia and perimeter fixing on thicker-profile mid-grey composite and timber boards

Frequently asked questions
When should I use DS65 over DS50 for stone grey and mid-grey decking?
Use DS65 when boards exceed 22mm thickness, on stair treads and high-traffic surfaces, or when fixing into hardwood or composite joist systems. For standard 20 to 22mm boards on softwood subframes, the DS50 in RAL 7042 is the appropriate specification.
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 mid-grey head suits grey-oiled, weathered, or grey-stained timber 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.
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 DS65 screws do I need for decking steps?
Allow approximately 6 to 8 screws per stair tread. A 10-step staircase typically requires 60 to 80 screws, covered by a single 100-pack with some to spare for riser boards.
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.
