When you’re halfway through a job and a nail snaps or a cable clip fails, you know it wasn’t a tiny mistake — it was a poor choice of fastener. The right nail, clip, or hanger keeps structures square, cables tidy, and fixtures secure. Think of fastening products as the unsung glue of a successful project: out of sight, but crucial to longevity and safety.
Nails and fasteners cover a wide range: general-purpose nails, capping nails for trunking, cable clips, conduit clips, dovetail cable hangers, and more. If you’re working with electrical trunking or cable runs, specialty items like capping nails and cable hangers are what make the job neat and code-compliant. Choosing the right type reduces rework and future problems.
Standard nails come in many lengths and gauges. For timber joinery, you’ll typically reach for nails that are 1/2 inch to 4 inches long, depending on the materials. Ring-shank or spiral nails offer extra pull-out resistance for decking or outdoor projects where movement and weather are factors.
Capping nails are designed for fixing capping or trunking covers without splitting the plastic; a common size used in trunking is about 1 inch long. Conduit clips and internal angle moulded clips make corner runs tidy — imagine snapping a neat corner cover into place instead of wrestling with loose clips and big gaps.
Cable clips for round cable are sold by the hundred, and they come in sizes to suit small data cables up to larger power cables. Dovetail cable hangers and cable rods keep runs suspended and tidy, especially in lofts or ceilings. Many tradespeople keep a couple of different clip sizes on the van for quick fixes.
Expert Electrical is a specialist supplier often stocked with trade-level electrical fixings you’ll struggle to find in general DIY stores. They list a solid mix of items like dovetail cable hangers that fit cables roughly 11/16 to 7/8 inch in diameter and packs of cable clips sold in hundreds — perfect for installers who want product consistency and reliability.
Examples of useful items you’ll see at a specialist supplier include dovetail cable hangers (for cable diameters around 11/16–7/8 inch), packs of 100 cable clips for round cable in black, and capping nails roughly 3/16 by 1 inch sold in 100-count packs. There are also conduit clips sized for about 1 inch conduit and internal angle moulded clips for trunking roughly 4 by 2 inches.
If you’re weighing up where to buy, the UK has a handful of reliable retailers catering to both trade and DIY needs. Each has its strengths — trade-focused ranges, value lines, or wide accessibility — so pick the one that fits your project and budget.
Screwfix is a go-to for contractors and serious DIYers. They have an extensive range of nails, galvanised fixings, and specialist clips that mirror many trade catalogues. If you want a broad selection and a predictable product spec, this is a strong starting point.
Toolstation often competes on price without skimping on range. From pack sizes in hundreds to trade quantities, you’ll find everything from general nails to specialist conduit clips and cable hangers. Their product descriptions are practical and aimed at people who know what they need.
B&Q and Wickes are great for homeowners and small tradespeople. They carry general-purpose nails, screws, and a selection of cable clips and trunking accessories. If you’re doing a one-off home repair and only need small packs, these shops are convenient and easy to navigate.
For builders and site work, Travis Perkins and Jewson stock heavier-duty fixings and trade packs. You’ll find larger box quantities and more industrial-grade options, from stainless steel nails for damp environments to robust trunking fixings for long runs on site.
RS Components and other electrical wholesalers are where electrical contractors often shop for specialist items like dovetail hangers, capping nails designed for plastic trunking, and conduit clips. These vendors focus on specification and consistency rather than bargain basics.
Choosing a fastener is about matching nail material, length, and head type to the job. Are you fixing into softwood, MDF, masonry, or metal? Different substrates demand different fasteners. For example, when securing plastic trunking, use capping nails around 3/16 by 1 inch so they hold the cover without cracking it.
Galvanised nails resist rust and are a sensible choice for outdoor or damp interior projects. Stainless steel is best near coastal areas or where salt spray is an issue. For indoor dry environments, plain steel may be fine but it’s worth stepping up if you want longevity.
As a rule of thumb, a nail should penetrate at least two-thirds of the secondary piece you’re fastening into. That means if you’re fixing a 3/4 inch trim to a stud, a nail around 1 1/4 inches long gives a secure bite without passing right through the other side.
Here are some real-world picks based on the types of items you’ll find at electrical specialists and trade suppliers, with imperial conversions for clarity.
These hangers hold cable runs neatly on cable tray or along ceilings. They typically come in packs of 100 and are ideal for suspension points where you want a secure, repeatable fix.
Round cable clips in black or white are sold in hundreds and are perfect for neat runs along skirting or behind trunks. They’re small, cheap, and save hours of untidy cable ties and slack loops.
Capping nails are designed to secure the cap of trunking without splitting plastic. Packs of 100 are common and ideal for installers who fit trunking regularly; the shorter length avoids cracking the cover when hammered or punched in.
Conduit clips keep conduit runs tidy and in place; moulded internal angle clips make neat corners for trunking runs — both save time and give a professional finish.
Having the right tools makes a small job feel like a pro job. Basic essentials include a good hammer, a selection of nail sets, a cordless drill with screwdriver bits, a stud finder, and a tool for cable staple setting if you use many clips. For trunking, a proper cable cutter and a deburring tool keep edges smooth.
When you’re working with cable runs and electrical fixings, always isolate circuits if you need to work near live cables. Wear eye protection when hammering in clips and use gloves to prevent splinters or cuts while handling metal fixings. Safety is not optional — it’s the clear line between a job done and a job that causes trouble later.
Buying in bulk is usually cheaper per unit, but only if you’ll use the stock within a reasonable time — nails and clips don’t take up much space and they don’t expire. Trade packs from wholesalers often reduce the per-item cost. Also, stick with reputable brands for specialty items; a cheap clip that fails will cost time and reputation, which is more expensive in the long run.
When comparing, look beyond the price per pack. Check the material, coating, and the exact usable length. Two products that look similar might perform very differently under strain or in damp environments. Comparison sites can help surface these specification differences so you can make an informed purchase.
Think long-term. Stainless or properly galvanised fixings reduce the need for replacement. Reusing good quality fixings where safe and appropriate is another easy win. Sustainable choices save money and material in the long run — and help avoid that familiar cycle of fix, fail, repeat.
Before you click “buy” or step up to the counter, make sure you’ve checked: the exact fixings needed (type and size in inches), the material and coating, pack quantity, and whether you need tools to install them. Keep a small stock of common sizes on hand so you don’t have to chase back to the store mid-job.
Choosing the right nails and fasteners is a small decision with a big impact. From specialist electrical supplies like dovetail cable hangers and capping nails to bulk trade packs for site work, the UK market offers options for every scale of project. Match the fastener to the material, pick the right finish for the environment, and buy from a reputable supplier — that’s a recipe for tidy, durable results.
Conclusion: invest a little time in selecting the correct nails, clips, and hangers and your project will thank you. The right fastener saves time, keeps installations looking professional, and prevents costly callbacks. Whether you shop at a specialist electrical supplier or a national retailer, a considered choice today is fewer headaches tomorrow.
