Plasterboard (also called drywall or gypsum board) is the most common internal wall surface in UK homes built or renovated since the 1960s. It’s lightweight, easy to work with, and provides a smooth finish — but it’s also soft, crumbly, and terrible at holding screws on its own.
Standard nylon wall plugs — the coloured ones designed for masonry — simply don’t work in plasterboard. The gypsum core crumbles under load and the plug pulls straight out. You need specialist plasterboard fixings, and choosing the right one depends on what you’re hanging and how heavy it is.
Plasterboard Fixing Types — Comparison Table
| Fixing Type | Load Capacity (12.5mm board) | Ease of Use | Removable? | Best For |
|---|---|---|---|---|
| Self-drill anchors (metal) | 10–20 kg | Very easy | Leaves small hole | Curtain poles, towel rails, light shelves, bathroom accessories |
| Self-drill anchors (nylon) | 5–15 kg | Very easy | Leaves small hole | Light hooks, picture frames, smoke alarms |
| Spring toggles | 15–25 kg | Moderate | No — toggle drops into cavity | TV mounts, heavy shelves, heavy mirrors |
| Gravity toggles (snap toggles) | 15–30 kg | Moderate | Yes — toggle stays accessible | TV mounts, heavy shelves, anything that may need future removal |
| Hollow wall anchors (Molly bolts) | 15–25 kg | Moderate | No — permanently deforms behind board | Medium to heavy loads, wall-mounted cabinets |
| Rubber nut anchors | 10–20 kg | Moderate | Yes | Where vibration resistance is needed, bathroom fixings |
Self-Drill Plasterboard Anchors
Self-drill anchors (also called speed plugs or Zip-Its) are the quickest and easiest plasterboard fixing. They have a coarse thread that cuts into the plasterboard as you drive them in with a screwdriver or drill. No pre-drilling required — just position and screw in.
Metal Self-Drill Anchors
Metal self-drill anchors offer better holding power than nylon versions and are the go-to choice for most household plasterboard fixings. A single metal self-drill anchor in 12.5mm plasterboard can hold 15–20 kg, making them suitable for curtain pole brackets, towel rails, toilet roll holders, and light shelf brackets.
How to install: Position the pointed tip against the plasterboard, drive it in clockwise with a Phillips screwdriver or drill (slow speed). Once the flange sits flush with the wall, drive your screw into the centre of the anchor.

Nylon Self-Drill Anchors
Nylon versions are cheaper and fine for lighter loads — picture frames, small hooks, cable clips, smoke alarms, and light decorative items. They hold 5–15 kg per fixing depending on the brand and plasterboard thickness.

Spring Toggles
Spring toggles are the heavy-hitter of plasterboard fixings. They consist of a bolt threaded through a pair of spring-loaded metal wings. You push the folded wings through a pre-drilled hole in the plasterboard, and they spring open behind the board, spreading the load across a wide area.
A single spring toggle in 12.5mm plasterboard can hold 20–25 kg — making them suitable for TV wall mounts, heavy mirrors, heavy floating shelves, and wall-mounted storage.
How to Install Spring Toggles
- Drill a hole in the plasterboard to the size specified on the toggle packaging (usually 10–13mm)
- Thread the bolt through the item you’re mounting (the bracket, plate, etc.)
- Screw the toggle wings onto the bolt
- Fold the wings and push them through the hole — you’ll hear them spring open behind the board
- Pull the bolt towards you to hold the wings against the back of the plasterboard
- Tighten the bolt while maintaining backward pressure until the bracket is secure
Important: Spring toggles are not easily removable. If you undo the bolt, the wings fall into the cavity behind the plasterboard and can’t be retrieved. For fixings you may need to remove later, use gravity toggles (snap toggles) instead.

Gravity Toggles (Snap Toggles)
Gravity toggles (often sold under the brand name SnapToggle) are a more modern alternative to spring toggles. They use a metal channel that passes through the plasterboard and snaps into position behind it. A bolt then threads through the channel to secure your fixture.
The key advantage over spring toggles: the channel stays in place permanently, so you can remove and reinsert the bolt without losing the fixing. This makes them ideal for TV mounts (where you might need to adjust or replace the TV) and anything that may need future maintenance access.
Load capacity is excellent — 25–30 kg per fixing in 12.5mm plasterboard, depending on the bolt size.

Hollow Wall Anchors (Molly Bolts)
Hollow wall anchors (commonly known as Molly bolts) use a metal sleeve that expands behind the plasterboard when you tighten the bolt. The expanded metal arms grip the back of the board, creating a strong anchor point.
They’re well-suited for medium to heavy loads — bathroom cabinets, kitchen wall units on plasterboard, large picture frames, and coat racks. Load capacity is typically 15–25 kg per fixing.
Installation tip: Use a hollow wall anchor setting tool (available from most tool shops) for a neater, faster installation. Without the tool, you can install them with a screwdriver, but the process is slower and the result less consistent.

Plasterboard Thickness Matters
UK residential plasterboard comes in two main thicknesses:
- 9.5mm: Older properties and ceilings. Lower load capacity — reduce the ratings above by roughly 25–30%.
- 12.5mm: The current UK standard for walls. The load ratings in this guide assume 12.5mm board.
- 15mm: Sometimes used in commercial settings or for fire resistance. Slightly higher load capacity than 12.5mm.
If you’re unsure of your plasterboard thickness, drill a small test hole and measure the depth before the drill breaks through into the cavity.
Can I Screw Directly into a Stud?
Yes — and you should whenever possible. If your fixing position happens to align with a timber stud behind the plasterboard, screw directly into the stud with a standard wood screw. No wall plug or anchor needed.
A single No. 10 × 75mm screw driven 40mm into a timber stud can hold 45–90 kg, far more than any plasterboard fixing. For heavy items like TV mounts, always try to get at least one (ideally two) fixings into studs.
Finding studs: Studs are typically spaced 400mm or 600mm apart (centre to centre). Use an electronic stud finder, or knock along the wall — it sounds solid over a stud and hollow between them. Stud finder — check price on Amazon
Frequently Asked Questions
Will normal wall plugs work in plasterboard?
No. Standard nylon expansion plugs (the coloured ones designed for masonry) do not hold reliably in plasterboard. The gypsum core is too soft to resist the expansion force — the plug either pushes through the back of the board or crumbles the plasterboard around it. Always use purpose-made plasterboard fixings.
What’s the strongest plasterboard fixing?
Gravity toggles (snap toggles) and spring toggles offer the highest load capacity — up to 25–30 kg per fixing in standard 12.5mm plasterboard. For maximum holding power, use multiple gravity toggles spread across the mounting surface.
Can I mount a TV on plasterboard?
Yes, but with the right fixings. For TVs up to 25 kg, use four spring toggles or gravity toggles — this gives a combined capacity of 80–100+ kg, providing a generous safety margin. For heavier TVs or articulating mounts that put extra stress on the wall, try to hit at least one or two studs. See our full TV mount fixings guide.
How do I fix into plasterboard on a ceiling?
Ceiling fixings are under constant gravitational load, so use the strongest option available. Spring toggles are the best choice for ceiling applications in plasterboard. Reduce the listed wall load capacity by about 50% for ceiling use. For anything heavier than a light pendant light, try to fix into the ceiling joists instead.

Recommended Plasterboard Fixings
The right fixing depends on the weight you need to hold. For light loads, self-drill anchors are quick and easy. For heavy items like TVs and shelves, spring toggles and SnapToggles are the professional choice.
