Flooring Screws
Floorboard screws stop squeaks, lift, and movement in timber and chipboard floors, giving a tighter fix that stays put under daily site traffic.
If you're pulling a floor back down after first fix or sorting boards that have started talking underfoot, use proper floorboard screws rather than whatever is rolling round the van. These are made for timber and sheet flooring, with lengths like floorboard screws 65mm for solid bite without punching through where you do not want it. You will also find screws for chipboard flooring and tongue and groove flooring screws that pull boards down tight, reduce movement, and leave a cleaner finish. If you need general Screws, dedicated Wood Screws, or a tougher all-round fixing from the Multi-Purpose Screws range, match the screw to the floor build-up and get it fixed properly.
What Are Floorboard Screws Used For?
- Pulling loose floorboards back down over joists stops movement and gets rid of the squeak that starts every time someone walks across a landing or hallway.
- Fixing chipboard flooring sheets during first fix gives you a tighter hold than nails, especially where trades will be walking the deck hard before second fix starts.
- Securing tongue and groove flooring screws into timber subfloors helps draw the board joints tight so edges sit flatter and do not start rubbing under load.
- Replacing lifted or damaged floor screws in refurbs makes patch repairs cleaner, particularly when you are lifting sections for pipework or cable runs and need the floor back solid after.
- Fastening floorboards in lofts, upstairs rooms, and landing areas gives maintenance teams a fix they can remove again later without wrecking the boards.
Choosing the Right Floorboard Screws
Sorting the right one is simple: match the screw length to the board thickness and the joist below, not just whatever is cheapest.
1. Length Matters More Than Anything
If you are fixing standard chipboard or timber boards, the screw wants enough bite into the joist without coming through where it should not. Floorboard screws 65mm are a common pick for thicker boards or where you want a more confident hold into timber below.
2. Match the Screw to the Floor Type
If it is sheet flooring, go with screws for chipboard flooring that are made to clamp the board down cleanly. If you are dealing with traditional boards, tongue and groove flooring screws or timber flooring screws make more sense because they pull the board tight without chewing the edge up.
3. Head and Drive Make a Difference
Do not ignore the drive type. A decent recess paired with the right Screwdriver Bits means less cam-out, fewer stripped heads, and quicker fixing when you are doing a full room rather than one awkward board.
4. Indoor Flooring Is Not the Same as Exterior Timber
For internal floors, stick with proper floor screws built for dry structural timber and sheet flooring. If the job is outside, step over to Decking & Exterior Screws instead, because indoor flooring screws are not the right answer for wet, exposed timber.
Who Uses These on Site?
- Chippies use floorboard screws during first fix and flooring repairs because they pull timber down tight and leave a floor that does not start creaking a month later.
- Sparkies and plumbers reach for screws for floorboards when lifting access runs, as they can get boards back down securely without smashing them to bits with repeated prying.
- Refurb teams and maintenance fitters swear by them for sorting squeaky upstairs floors, patching chipboard, and re-fixing boards after inspection work.
- House builders and snagging teams use flooring screws to tidy lifted edges, loose sheets, and movement around doorways before handover.
Flooring Screw Accessories That Save Time
A couple of simple add-ons make re-fixing floors quicker, cleaner, and far less annoying.
1. Screwdriver Bits
Use the correct bit for the screw head and keep a spare in your pouch. It saves rounded recesses, slipped drivers, and that pointless fight with one screw when you have a whole room still to pin down.
2. Bit Holders
A proper bit holder helps when you are running fixings into awkward corners, tight edges, or under radiator tails where a chunky driver nose gets in the way.
3. Countersink Drill Bits
If you are working with older timber boards that like to split or sit proud, a quick pilot and countersink leaves a neater finish and helps the screw pull down flush.
Choose the Right Floorboard Screws for the Job
Use this quick guide to match the fixing to the floor you are pulling down.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Fixing 18mm chipboard flooring to joists | Chipboard flooring screws | Sharp point, thread designed to pull sheet flooring down tight, clean countersunk finish |
| Re-fixing loose timber floorboards in a refurb | Floorboard screws | Strong hold in joists, easy future removal, less movement than nailed boards |
| Pulling down thicker boards or getting deeper bite | Floorboard screws 65mm | Extra length for better purchase into joists, useful where boards have started lifting |
| Securing tongue and groove boards neatly | Tongue and groove flooring screws | Designed to clamp boards together, reduce rubbing, and keep edges sitting flush |
| General timber fixing where the job is not strictly flooring | Standard wood screws | Good all-round option, but check thread, head, and length before using them as floor screws |
Common Buying and Usage Mistakes
- Choosing screws that are too short means they only just catch the joist, so the board works loose again and the squeak comes back. Check board thickness and allow proper bite into the timber below.
- Using random leftover screws from the van often leads to poor pull-down, stripped heads, or heads sitting proud. Proper floor screws are made to clamp boards tight and sit flush.
- Driving fixings straight into older dry timber without a pilot can split the board edge or leave it riding up. On touchy boards, pre-drill and countersink rather than forcing it.
- Missing the joist is more common than people admit, especially on patch jobs. Mark your joist lines properly or you will just pin the board to fresh air and wonder why it still moves.
- Using interior flooring screws on outdoor timber is the wrong fix for the job. If the timber is exposed to weather, use an exterior-rated alternative instead.
Floorboard Screws vs Wood Screws vs Multi-Purpose Screws
Floorboard Screws
These are the right choice when the job is fixing or re-fixing floors. They are designed to pull boards down tight, reduce movement, and make later lifting less destructive than nailed floors.
Wood Screws
Standard wood screws can work in timber, but not every one is ideal for flooring. They are better where you need a general timber fixing and less ideal where you want clean pull-down across lots of boards.
Multi-Purpose Screws
These are handy if you want one fixing for mixed jobs, but flooring-specific screws usually do a better job on chipboard and floorboards. If the whole task is floors, buy for that job rather than trying to make one screw do everything.
Maintenance and Care
Keep Boxes Dry
Store floorboard screws somewhere dry in the van or workshop. Damp cardboard boxes and loose fixings rolling about soon lead to corrosion and wasted stock.
Use the Right Bit
Worn bits damage screw heads fast, especially when you are driving hundreds in a day. Swap bits before they start slipping and chewing out the recess.
Clear Dust Before Re-Fixing
If you are reusing lifted boards, clean out old dust, debris, and broken fixings first. The board will sit flatter and the screw will pull it down properly rather than trapping rubbish underneath.
Replace Damaged Fixings
Do not reuse bent or chewed screws on flooring repairs. Fresh fixings cost little and save you having to revisit a board that starts moving again.

Floorboard Screws FAQs
What size screws for 18mm floorboards?
For 18mm floorboards, most trades look for enough length to pass through the board and still get a solid bite into the joist. Around the 50mm to 65mm mark is common, with floorboard screws 65mm often used where a stronger hold is needed. The main thing is proper purchase into the joist without going too deep for the build-up below.
How to screw down loose floorboards?
First find and mark the joists properly. Pull the board tight to the joist with suitable floor screws, and on older dry timber it is worth pre-drilling to avoid splitting. If pipes or cables may be below, check before driving anything in. Done right, the board will sit flat, stop moving, and the squeak usually goes with it.
What length floorboard screws do I need?
Match the screw length to the board thickness and how much bite you need into the joist. Thin boards do not need the same fixing as chipboard sheets or thicker timber boards. As a rule, you want enough thread into solid timber to clamp the floor down properly, which is why lengths like 65mm are popular on a lot of site jobs.
Can you use flooring screws on chipboard flooring?
Yes, that is exactly what many of them are for. Proper screws for chipboard flooring are designed to pull the sheet down tight to the joist and help stop movement between boards. They are a better bet than grabbing generic fixings and hoping for the best.
Do flooring screws need pre-drilling?
Not always. Many flooring screws are made to drive straight in, especially into chipboard and standard softwood. That said, if you are fixing older hardwood boards, brittle timber, or close to an edge, a pilot hole is the safer move and usually gives a cleaner finish.
Are floorboard screws better than nails for squeaky boards?
Yes, in most repair jobs they are. Screws pull the board down tighter and are far less likely to work loose again once people start walking over the area day in day out. They also make future access easier if the board needs lifting for services.
