One of the questions I get asked regularly is how to fix heavy items such as a TV to plasterboard or drywall. Unfortunately there are no plasterboard fixings available that I would trust to hold up a 65 inch TV that has cost hundreds of pounds, as even the best plasterboard fixings cannot support enough weight for them to be effective for this job as they all rely on the strength of the plasterboard itself. By locating the studs and fixing to them you are guaranteed to get the best fixing available and guarantee that your expensive TV will not end up on the floor in several pieces.
I tested out some plasterboard fixings in a previous video, the results of which are interesting-

In this video I look at how to remove some rounded screws by using everything from an elastic band to a dedicated damaged screw removal bit. The 7 techniques used in this video are-
Damaged screw remover
Trend Grab it pro
Left handed drill bit
There is no one method that works on all screws and if you get a long wood screw with a rounded head you have not much chance of removing it.
Fixing to insulated drywall can be very difficult. In this demonstration I use space-plugs to bridge the gap between the item being fixed and the external wall. Fixing to an insulated wall is much easier if you use the space plugs. Some insulated drywall can be as think as 90mm, making it difficult to get a good fixing but by using the space plugs you are guaranteed to get a good fixing.]]>
GripIt fixings are a quick and easy way of fixing to plasterboard or drywall. These fixings are easy to use and currently come in four different sizes depending on what you are fixing to the plasterboard or drywall. Currently 4 different GripIt fixing are available- Yellow 15mm, Red 18mm, Brown 20mm and blue 25mm. GripIt fixings were made famous when they appeared on Dragons' Den and were backed by Deborah Meaden.]]>
Dewalt wall dogs are an all steel, tension free, one piece threaded fastener that is suitable for use in most substrates including concrete, stone, brick, plasterboard and timber. When using the dewalt wall dogs in concrete, brick or masonry it is a good idea to drill a test hole to ensure you drill the correct diameter hole for the wall dogs to work correctly. In most instances when fixing to masonry you will need to drill a 4mm diameter hole. These fixings can be used to fix items that are 3mm or less in thickness. They are very quick and easy to use and leave you with a non-combustible fixing. The Dewalt wall dogs are available in countersunk, pan head, countersunk white head and pan head white.
Currently the Dewalt wall dogs are available as follows-
DFM424015P- Wall-dog countersunk head- chrome
DFM424000P- Wall dog countersunk head- White head
DFM425005P – Wall dog pan head- chrome
DFM425000P – Wall dog pan head – white head
Shear nuts are a security nut that are very difficult to remove without specialist tools, as their name implies the head of the nut shears off leaving behind a dome shaped nut which is very difficult to grip, making removal very difficult. The shear nuts used in this video are stainless steel M10 and require considerable force to shear the hexagon part from the body of the nut, these cost about £1 each. You can also get cheaper glavanised versions, they come in several bolt diameter sizes from M6 to M16.]]>
Concrete screws are a really fast and easy way to fix to masonry. Once the correct drill bit has been selected you can use these fasteners really quickly as there is no messing about- just drill the correct size hole and then screw the concrete screw into the hole!]]>
Clutch head screws are a security screw which are designed to be difficult to remove with a normal screw driver. This video shows how to drive in clutch head screws, the important thing is to drill a pilot hole so that the screws do not get stuck when driving them in. Clutch head screws are useful for fixing external hinges to outbuildings or garages, where a normal screw can be removed and access gained to the building.]]>
Hollow wall anchors such as rawlplug intersets or Mollys can sometimes be installed without using the special setting tool, but in drywall that is not plastered the setting tool is essential. The cost of the hollow wall anchor setting tool is about £8 to £20 depending on which one you buy. http://fave.co/1PLlTLt]]>
Resin anchors are a great way of fixing to many substrates including Brick, concrete and stone. Because resin fixings do not rely on expansion force, they can be used in places where traditional fixings that rely on expansion cannot be used such as close to the edge fixing.]]>
Concrete anchors are a heavy duty anchor for fixing objects to masonry surfaces. Here we use a thru bolt to demonstrate how to fix a piece of wood to a concrete slab. One problem with thru bolts is that they are extremely difficult to remove and so here we have drilled the hole much deeper so that the old thru bolt can be knocked into the hole.]]>
How to use hollow wall anchors to fix to drywall without using the setting tool. This can be done providing the drywall has been skimmed with plaster, if it has not it is advisable to use the hollow wall anchor setting tool.]]>
Buy snaptoggles here- http://fave.co/1Ozdquh
snaptoggles are a great way of fixing to hollow plasterboard walls. These plasterboard fixings are extremely easy to use and are one of the best fixings for plasterboard that I have used. If you need a strong and secure fixing for drywall there is nothing better than the Snap Toggle.
Spring toggles are commonly available in most countries and can be used for fixing medium weight items to hollow plasterboard walls. Here we demonstrate how to use spring toggles as well as the disadvantages of using them. Spring toggles are widely available and are one of the easiest to use drywall fixings, but if you remove the screw the fixing will get lost in the void.]]>
Fixing to drywall can be achieved several ways, here we demonstrate a few methods of fixing to drywall or drywall that has been used in a hollow wall construction that consists of a wall that is build from timber studs and plasterboard/drywall sheets.]]>
Rigifix wall anchors are ideal for fixing heavy items to plasterboard walls that have a solid wall behind. Fixing heavy items to solid walls that have been drylined can be difficult as normal fixings can be problematic, The rigifix anchor provides an extremely solid fixings in such walls. If your wall has been dry lined using the dot and dab method these fixings work brilliantly as they fix into the wall behind without the risk of damaging the drywall.]]>
Timber thread inserts are very useful as they can be tightened and loosened an unlimited amount of times. If you tighten and loosen a normal wood screw eventually it will enlarge the hole and will not grip as well, by using timber thread inserts you can overcome this problem. The timber thread inserts are also self-cutting so you simply drill the correct size hole and the insert will cut its own thread when it is screwed into position. Timber thread inserts can also be used when fixing to the edge of another piece of timber, making them extremely useful.]]>
