Mechanical anchors are currently used in a wide range of reinforcement applications. Many customers are still not very clear about the classification of mechanical anchors. In particular, the distinction and understanding of the self-cutting mechanical anchor and the rear-expanding mechanical anchor are not very sufficient. Today, we will talk in details about the difference between the self-cutting mechanical anchor and the rear-expanding mechanical anchor.
First of all, we must know that there is an alias
for the rear-expanded mechanical anchor, which is the mechanical anchor of the rear cut bottom. Therefore, we can find that the difference between the names of the two mechanical anchors is self-cutting and back-cutting. So what is self-cutting and what is the back-cutting? Simply put, whether there is a ring shearing edge on the mechanical anchor or not, and whether it needs to be reamed during installation.
The self-cutting mechanical anchor is generally an anchor that cuts the substrate out of the wedge-shaped hole and expands in the hole by the ring-shaped cutting edge through the bottom expansion portion when it is installed to achieve the purpose of mechanical locking. It is easy to install and does not require additional reaming.
While the rear-expanding mechanical anchor bolts are generally expanded by using a special drill bit before the corresponding anchor bolts are installed. Different types of rear-expanding anchor bolts have different punching requirements, which means that different drill bits are required according to different situations when installed.
Whether it is a self-cutting mechanical anchor or a rear-expanding mechanical anchor, as long as the appropriate scene is selected, it can bring positive effects to the project. As a professional mechanical anchor manufacturer in Nanjing, Mankate has supplied mechanical anchors for 15 years to engineering projects across the country. Whether it is self-cutting mechanical anchor or rear-expanding mechanical anchor bolts, all types of mechanical anchors are sold, and the quality is excellent. Welcome to buy.
