Metal Corner Brackets

I'll switch my bits over one of these kids are always handy to have we've got our square drive right here hopefully you guys can say that so this is the drill bit that we use for our square drive you can say they're the tip is actually square and we'll take our decking screw which has a square tip on there and we'll drill this one here in so that the square one prevents out wobbling from the top and also helps you stabilize it so that you don't actually strip it it doesn't work fairly well you can see there a lot more control by Metal Corner Brackets putting that in the ones on the right either have a washer or a little bit of a wider head and they're designed to sit above the surface they're going to be exposed screws and they're designed to not penetrate through that material so I'll show you guys how this one here drives in we've got a wafer head or a flat button head on top so this one here remembering is going to sit above the surface put it through some timber and you can see right there just sits right above that surface it's got a little flat dome or little flat button on top.

I'd assume that's where it gets its name from the button head so you can see there that one's nice and flush we're going to use the external hex drive nail so this one here and we use an eye socket to drive that one there in this one he has absolutely almost zero slippage still a little bit wobbly but in terms of slippage works very very well especially when you've got a lot of torque and a lot of power coming through the drill and into that tougher material you want to make sure that the hex head drive is one of the ways to go because you prevent any of that slippage very very easy to control it all the way through so these are the main types of screws Outdoor Screws that you'll be using whether you using bugle was countersunk or the drywall screws all of them will have a tapered head on the top and that allows you to sync those into the material the other lines are going to basically have a head that's a little bit wider more surface on top to be able to stop penetrating through that actual material.

So these are the main ways to be able to identify and differentiate between the screws whether it's going into the material flush below the surface or above the surface here now when we have a look at the shank of the screw they come in a whole range of different lengths and also diameters so the thickness of the screw is called the gauge of the screw the most common gauges are 6 8 and 10 the higher the number the thicker the gauge of the screw so here we've got a 6 gauge screw up on top and then down the bottom we've got a 12 gauge screw so.
