Today we are going to share with you the specifications and types of cement floor nails and geckos, as well as the drill tail sizes and specifications used. Now let’s take a look at what we have here. The right hand side belongs to the gecko type, and the left side belongs to the wall nail type. Generally speaking, those with a sleeve are called geckos, and those without a sleeve are like nails, which are called wall nails. These are called No. 8 cement wall nails
, and these are called 1/4-inch cement wall nails. For No. 8, he uses a cross head screw. If this type is thicker, he uses a hexagonal head. You must use a hexagonal sleeve. For cement wall nails, you can use No. 2 screws. This type of screwdriver can be used . The drill and lock part was introduced last time. If you are interested and want to see more details, you can go back and watch my video. This is a 7.5mm socket. This is a special specification . 7.5 is not 6. It's not No. 8. The thickness of No. 8 is about the same as ordinary screws, so the strength is average. What can you use it for? For example, you can just drill a hole and lock a screw , and then you can hang a moon or a clock. The lighter ones are the heavier ones. For example, if you want to nail that wall cabinet to the wall, you need this kind. Then this kind is thicker and longer. Let’s sort out the specification and call it #8. This is 1/4 inch. No. 8 also has different lengths. For example, they usually say #8*1 inch , and #8*3/4. Generally, #8 is shorter, about 1 inch. The general length of this kind is 1/4 inch. The longer ones are usually 2 inches, 2 and a half inches or 3 inches. Why ? Because it is used to lock the corner wood on the wall. The corner wood is usually already 1 inch . Your length must be at least 2 inches or more. The 1/4 I just mentioned. It refers to this width. Why do we need to know the width of the screw? Because we need to know what kind of drill bit to use to drill . If you drill the hole too big , the screw will not be locked tightly . We will use No. 8. Use a 3mm cement drill bit to drill the 1/4 inch on the right hand. We have to use a 5.8mm cement drill bit. I found on the solid base that this one is made of stainless steel. These ones are all made of stainless steel , but I found It's just that the hole I drilled with the 3mm is a little bit smaller because I used an impact driver to lock it and the head would break, so when you are drilling, just give it a few more strokes to let you drill the 3mm one . The hole is slightly larger , so it will be easier to lock. For your reference, the part of the wall nail looks like this. It is not very safe without a condom, but it is not safe, but it does not need a condom. Hahaha, OK, just drill. If the hole is directly locked, then this side is the lightest gecko, which is this kind of plastic gecko. For plastic geckos, we usually use a 6.5mm drill tail to drill the hole , and then use a hammer to knock the screw into the hole and then lock it. When the screw is locked in this hole, it will stretch out and push against the hole, and then it will be tight. But because this is made of plastic, you have to pay special attention to this and not over-lock it , because the plastic tooth quilt inside is over-locked . If you lock it a few times , it will be damaged by you and it will not lock tightly. When you buy it, you can confirm with the boss that you want a plastic nail set with a 6.5mm drill tail , so that you are less likely to buy a thinner one . The small nail covers are made of plastic. You can tell at a glance that they are metal. I have prepared two sizes here. In fact, these are also three sizes. But I mean there are two sizes in terms of thickness. This is The 2-point one is 2 and a half points. The 2-and-a-half-point one is just different in length. Its thickness is the same. The more commonly used ones are 2 points/2 and a half points and 3 points. The so-called 2 points does not refer to the width of the sleeve. When you measure this sleeve, 2 points is 6mm. You see, this measurement is wrong . It is not 6mm. The 2 points is about 8 mm, so the 2 points refers to the screw inside. You see, the screw is almost 6mm when measured. 2 Points refer to the screw inside, 2 points , not the sleeve on the outside. Let me remind my friends that this place at the bottom is anti-slip. The anti-slip should be facing the sleeve , and it also has a slight cone here. The shape
is to stuff it into the tube. There is a gasket here. This side is the wall, and this side is inside the wall. So when you stuff it into the wall, this side is the wall, and this side is the outside. When you lock, lock, lock like this If you tighten this tail, it will be pulled into this and this will expand. So why is this type of expansion screw called an expansion screw ? Because it will expand. This is 2 points. 2 points refers to the screw inside. 2 points. Then this is 2 and a half points. What is 2 and a half points ? 2 points is 6 ? 3 points is 9.
Two and a half minutes is about 7.5. So the thickness of the screw inside is about 7.5. The sleeve on the outside is about 10. When we are drilling 2 If you want to drill a 2-and-a-half-minute drill, you need to use a larger one. The larger one means that you need to use an 8mm drill tail, which is about 2 and a half minutes. Generally, the end of a brick is about 8 mm. To drill a 2-and-a-half minute drill, you need to use a larger one, which is 3 minutes. When it comes to points, we usually use 9.5mm. Remember, it needs to be one size larger. For example, if you say 2 points for gecko, then your size is 2 and a half points. If our size is 2 points, it will be 3 points, 2 points,
2 and a half points, 3 points. The three points jumped like this don't seem to be three and a half , and then the four points are jumped. In addition to the specifications of two points and two and a half minutes, the other is the length. For example, two and a half minutes, 2 inches long, two and a half minutes, 2 and a half inches, 2 inches long. Half is this length. I will simply share it with you here today.
