We have never had a problem with Fixfirm, it’s right on our doorstep, very rarely is there something not available, staff are always friendly and helpful." Screw diameter is usually measured in millimetres but “screw gauges” are sometimes used instead. Screw gauges are imperial measurements that don’t always have exact metric equivalents. The most common types of wall plugs can be split into three categories: universal wall plugs, expansion wall plugs and self-drilling plugs. Universal Wall Plugs Plastic wall plugs, often referred to as Rawl plugs are available in Yellow Red and Brown and are very convenient for DIY lightweight applications.
As their name implies, these plastic or nylon wall plugs can be used in a multitude of scenarios. They can be installed in solid materials, like stone and timber, and in hollow cavities. Identifying wall plugs and understanding their maximum weight restrictions is paramount – never skimp on safety. Frequently Asked Questions Which drill bit wall plug lasts the longest?All wall plugs get weaker over time. Heavier loads will decrease a wall plug’s effective lifespan. What size drill bit for 6 mm wall plugs? We can deliver bulky products and items that are up to six metres long. For larger consignments, we use a reliable pallet network with book-in and tail-lift options, if required.
You can get away with using smaller drill sizes than necessary. However, the grip between the screw and drill head reduces significantly as the drill bit size decreases. Self-drilling wall plugs have a large screw at their base: this is preferably made from metal, as the entire wall plug needs to cut cleanly through the material.The drill bit size is the maximum diameter of the drill head (i.e. a power drill or a screwdriver) that can be used. These Cut to length plastic wall plug strips sometimes referred to as cut to size are ideal for general purpose tasks provided the correct drill size is used with a suitable screw. These long wall plug strips are 300mm (12”) and are easily cut to the length required for each application. The screw self-centres in the plug pushing the 3 external fins against the sides of the hole preventing rotation. Modern wall plug designers have exploited this scientific phenomenon to create expansion wall plugs that can twist into strong shapes in a variety of materials. Expansion Wall Plugs
Fortunately, the wall plug fixings manufactured for UK and EU markets are standardised; they come in predefined metric measurements (millimetres, to the nearest 0.5 mm ) and sometimes imperial screw measurements (gauge). The correct-sized threaded screw is then screwed into the universal wall plug – consult the drill bit to wall plug comparison table above for further guidance on wall plug sizing! Use a 10 mm diameter drill bit for most 10mm wall plugs; the imperial equivalent is a 14 gauge drill bit. A 10 mm wall plug is likely to be grey or blue in colour. Unlike their universal counterparts, expansion plugs have fins that separate outwards from one another as the screw moves into the plug. The fins push against the material in all directions.
Orange 10mm Wall Plug Strip 30cm
For example, you could have two orange-coloured nylon wall plugs – both 34 mm long and 6 mm in diameter. One could be an expansion plug, capable of handling stresses of up to 70 kg or more . The other could be a universal wall plug with a maximum weight capacity of 5 kg or less! These are used in soft stones (i.e. sandstone), timber and to attach plasterboard to stud framework. Wall Plug Weight Limits Zinc-coated metal wall plugs can last considerably longer, so long as the zinc coating isn’t compromised by rust. As the screw twists into the plug, the universal plug’s exterior fins should twist and retract, gripping onto the surrounding material. Please note plastic wall plugs are not suitable for hollow stud walls, plasterboard, dry-lined and lathe and plaster walls.
Our trade counter service provides you with access to a friendly and efficient service and advice. Please note - ideally we ask for 30 minutes’ notice to be sure you aren’t kept waiting. How do I return faulty items? More expensive universal plugs will use both nylon and plastic. The two materials deform predictably in different ways. Nylon can withstand more heat than plastic and is used to secure heavier items, however the cut to length is a superbly versatile product.

They’re usually installed by first drilling a pilot hole. The universal wall plug is then lightly tapped into the pilot hole until flush with the material’s surface. Our Customer Service Team is available from between 7 am and 5 pm, Monday to Friday on 0800 594 44 44. Do you have any customer testimonials? Plastic and nylon wall plugs should have a usable life of 20+ years from manufacturing. Light, heat and water can discolour these plugs over time and gradually reduce their strength.
