Nail-Clips - 100pcs
- Product: Nail clips (circle cable clips) for surface-fixing round cable
- Pack Size: 100 pieces
- Sizes Available: 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 20 and 25 mm
- Important: The size is the cable diameter the clip holds — not the nail length
- Shape: Circle (round) — for round cable, not flat
- Construction: Moulded plastic clip with a pre-fitted steel nail
- Fixes To: Brick, plaster, and timber
- Use: Running cable neatly along walls, skirting, and ceilings
Nail Clips are the small plastic clips with a nail already fitted, used to fix cable neatly along a wall, skirting board, or ceiling. One tap of a hammer and the cable is held in place. This is the 100-piece pack, available in twelve sizes from 4 mm to 25 mm.
The number in each variant is the cable diameter the clip is made to hold. It is not the nail length and not the width of the clip itself. Getting this right is the whole job: a clip that is too small crushes the cable’s insulation as you drive it home, and a clip that is too large lets the cable slide and sag between fixings. Measure the outside diameter of your cable, sheath included, and match it.
These are circle clips, shaped for round cable — round mains flex, coaxial, CCTV, network and speaker cable. Flat twin cable needs a flat clip instead; a round clip will not grip it properly and a flat clip will not close around a round one.
Choosing the Right Size — Please Read
- The size is the cable diameter, not the nail. A 6 mm clip holds a 6 mm cable — it does not have a 6 mm nail
- Measure the outer diameter of your cable, including the outer sheath. That is what the clip grips. Vernier callipers give the reliable figure; a ruler across the cable is usually close enough
- If you are between sizes, go up rather than down. A slightly loose clip lets the cable move; a tight one crushes the insulation, and damaged insulation on a mains cable is a genuine hazard
- Buying for a job with several cable types? Measure each one — a network cable and a mains flex on the same wall will usually need different clips
- These are circle clips for round cable. Flat twin cable needs a flat clip
- Not sure which size you need? Send us a photo of the cable with a ruler alongside it and we will tell you
Key Features
- Nail already fitted: No separate fixings to hold, drop, or lose — position the clip and tap once
- Twelve sizes from 4 to 25 mm: Match the clip to the cable rather than making one size do
- 100 pieces per pack: Enough for a full room or a complete cable run
- No drilling required: Goes straight into brick, plaster or timber with a hammer
- Keeps cable off the floor: Fixed runs are safer and far tidier than trailing cable
- Plastic body: Insulates the nail from the cable it holds
Size Chart
| Clip Size | Holds cable of this outer diameter | Broadly suits |
|---|---|---|
| 4, 5, 6 mm | 4–6 mm | Thin signal and communication cable |
| 7, 8, 9, 10 mm | 7–10 mm | Standard round cable — the most commonly used range |
| 12, 14, 16 mm | 12–16 mm | Heavier multi-core and sheathed cable |
| 20, 25 mm | 20–25 mm | Large-diameter cable and small conduit or tubing |
Always measure rather than assume. Cable outer diameters differ between manufacturers even for the same specification, so the same cable type can need a different clip depending on who made it. Measure the cable you actually have.
Fitting Them Properly
Practical Notes
- Check what is behind the wall first. You are driving a steel nail into it — scan for buried cable and pipework before you start, particularly near switches, sockets and above worktops
- Run the cable loosely along its intended line and mark the fixing positions
- Space the clips evenly, roughly every 20–30 cm on a horizontal run, and closer on a vertical one where the cable’s own weight pulls down
- Position a clip within a few centimetres of every corner and every direction change, so the cable turns cleanly instead of bowing
- Hold the clip over the cable and drive the nail with light taps — stop as soon as the clip sits against the surface
- Do not over-hammer. Driving the clip in past flush crushes the insulation, which is the most common way a good cable run is spoiled
Where these are used
- CCTV installation: Running camera cable along walls and eaves
- Network and telephone cabling: Neat surface runs where chasing the wall is not an option
- TV and satellite: Coaxial cable from the dish or point to the set
- Speaker and AV wiring: Keeping cable off the floor and out of the way
- Surface electrical runs: Tidying cable along skirting, ceilings, and outbuildings
- Rented and finished properties: Adding a cable run without cutting into walls
1) Does the size refer to the nail or the cable?
The cable. A 6 mm clip is made to hold a cable of roughly 6 mm outer diameter — it does not have a 6 mm nail. This catches people out, so measure the outside diameter of your cable, sheath included, and order the matching size.
2) What happens if I use the wrong size?
Both directions cause problems. Too small and the clip crushes the insulation as you hammer it, which on a mains cable is a genuine hazard. Too large and the cable slides within the clip and sags between fixings. If you are between sizes, go up rather than down.
3) Will these work on a concrete wall?
They are designed for brick, plaster and timber, where the nail drives in with a few taps. Dense concrete and hard stone are much harder going and the nail may bend rather than penetrate. For concrete, a drilled fixing or an adhesive-backed clip is the more reliable approach.
4) How many clips will I need?
As a working figure, allow one clip every 20–30 cm on a horizontal run, plus one near every corner and direction change. A 100-piece pack covers roughly 20 to 30 metres of run at that spacing — enough for a typical room or a full camera cable route.
5) Can I use these for flat cable?
No. These are circle clips, shaped to close around round cable. Flat twin cable needs a flat clip — a round clip will not grip it, and the cable will work loose.
