Great Things About wall plugs

Wall plugs requirement brick, block or concrete to hold well.

Plaster just will refrain from doing, since it has very little holding power.

It's typically way too soft you see. Sure, if the wall is plastered with difficult cement render and thin skimming coats, you might get away with some light to medium loads, however generally the plastic plug needs to be pressed into the wall itself so it's whole length enjoys a brick, a block or concrete and so on

Many people want to know wall plugs. Due to the fact that the way a wall plug works and keeps in location is by broadening in a radially outwards style. Simply put, when you put a screw into a plastic wall plug (or an old made wooden plug for that matter) it serves as a wedge, pressing the two halves of the plug apart and filling the hole extremely tightly. Friction then takes care of waiting in place for all eternity; helpful things friction ... and it's free!

A lot of wall plugs are just 1 1/4 ″ to 1 1/2 ″ (32 to 38mm) long and most plaster on walls is in between 1/2 (12.5 mm) to 3/4 (19mm) or so thick. So, doing the maths and taking the thickness of the plaster far from the length of the plug you'll find out that very little of the plug is actually going into the brick/block/concrete if you leave them flush with the plaster. Likewise, the front part of the brick is unable to take much load either without running the risk of a 'fisheye' breakout under load.

Wall plugs work best when their ENTIRE LENGTH is fully inside the walls primary building product, hence easing the plaster and the front face of the walling material from stress.

Ways to set up plastic wall plugs

• Mark out all your holes using a spirit level and/or measuring tape.
• Thoroughly drill your holes, starting off slowly (perhaps with the hammer action off) till the drill bit forms a shallow hole (see pic above for depth), speed up and hammer back on to end up the hole.
• Vacuum out the hole if you want to be really correct, mainly not needed or done nevertheless ... Push or tap your rawlplugs into your holes, flush with the plaster.
• Position the item to be fixed over the hole and put the screw through it and into the plug, twisting the screw a tiny bit by hand till it bites.
• Sometimes the above step is easier if you press the screw all the way through the item and after that you'll quickly get the pointy end of the screw into the plug, sliding the product down the screw till it satisfies the wall.
• Using a little hammer tap the screw to press the plug through the plaster and into the wall itself and stop when the length of screw standing out equals the length of the wall plug.
• Tighten up the screw, taking care not to promote the very first few turns or you may press the plug in deeper (bad).
• Working in this manner ensures the plug is precisely the best depth into the wall and the screw will go all the way to the end of the wall plug when pulled up tight.
• Perfect. Rinse and repeat with the other screws.
• Put the kettle on or visit the refrigerator depending upon the time of day ...
