How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
M4.5 x 50 Brown Decking Screws for reliable board-to-joist fixing in hardwood, softwood, and treated timbers.
Each screw is manufactured from Ruspert-coated steel, featuring a durable three-layer metallic coating of zinc, film, and ceramic.
This advanced finish offers excellent corrosion resistance and a subtle, low-visibility appearance that blends seamlessly with stained or dark decking boards.
The countersunk head draws boards tight for a flush, professional finish with reduced movement and creak.
A sharp, coarse thread provides fast bite, controlled driving, and dependable pull-down across typical decking substrates.
Features & Benefits
- Exterior durability: Hardened carbon steel with corrosion-resistant coated finish for outdoor decking conditions.
- Flush finish: Countersunk head clamps boards to joists for a smooth walking surface.
- Fast bite: Coarse single thread and sharp point promote rapid insertion and strong pull-out resistance.
- Timber compatibility: Suitable for softwood, many hardwoods, and pressure-treated joists; pilot drilling recommended for dense boards and near edges.
- Visual blend: Brown coating helps minimise head visibility on darker or stained timber.
- Nominal size: M4.5 x 50mm.
- Tub quantity: Supplied in a tub of 500 for efficient deck coverage and fewer on-site restocks.
Applications
- Standard decking boards: Secure fixing of common board thicknesses to timber joists.
- Timber joists: Reliable bite and pull-down for subframe connections.
- General outdoor carpentry: Suitable for trims, steps, and perimeter details.
Installation Guidance
- Pilot & clearance: Pilot dense hardwoods and pre-drill near board ends to limit splitting.
- Driving technique: Drive at moderate speed with steady pressure; avoid over-torque that can strip fibres.
- Head seating: Countersink until flush; do not bury the head below the board surface.
- Good practice: Maintain consistent board gaps and fix each board with two screws per joist line.
Compliance & Performance
- Manufacturing reference: Produced to relevant timber fastener requirements (EN 14592 reference for mechanical fasteners).
- Corrosion protection: Exterior coated finish suitable for typical residential exposure; check local exposure class.
- Substrate suitability: Use with timber and most composite-over-timber installs; verify composite manufacturer guidance.
- Safety: Wear eye protection; support boards during fixing.
- Important note: For aggressive/coastal environments or permanent wet areas, specify stainless steel grade fasteners.
