What are the precautions for installing machine screw anchor

In buildings, bridges, tunnels and various industrial facilities, mechanical anchor bolts are a key fastening connector, and their importance is self-evident. The installation quality of anchor bolts is directly related to the stability and safety of the structure. Therefore, it is particularly important to ensure the standardization and scientificity of its installation process.
Before installing mechanical anchor bolts, accurate measurement and positioning are required first. This link is crucial because the installation position of the anchor bolt directly affects its fixing effect and overall safety. It is recommended to use high-precision measuring tools to ensure the flatness and crack-free installation position while meeting the design requirements. In addition, the bearing capacity and safety conditions of the surrounding environment must be considered comprehensively to prevent anchor bolt failure due to environmental factors. Yuyao Nanshan Development Co., Ltd.'s mechanical anchor bolt products are all accompanied by detailed installation parameter tables to guide users to select the appropriate drilling diameter and depth to ensure the accuracy of the installation position.
Drilling is a key link in the installation process of mechanical anchor bolts. According to the specifications and models of the anchor bolts, it is crucial to select a suitable drill bit for pre-drilling. The diameter and depth of the drilled hole must be strictly in accordance with the installation requirements of the anchor bolt to ensure that the anchor bolt can be fully embedded in the hole wall to form a firm anchoring effect. During the drilling process, the verticality and accuracy of the drilled hole must also be strictly controlled to avoid affecting the anchor bolt's fixing effect due to deviation.
The hole cleaning step should not be ignored either. After the drilling is completed, the hole must be thoroughly cleaned with tools such as a hard brush, air compressor or strong fan to remove impurities and dust. The purpose of this step is to ensure that the anchor bolt can fit tightly with the hole wall during installation, thereby improving the fixing effect. Yuyao Nanshan Development Co., Ltd. recommends that special attention be paid to the cleanliness of the hole mouth when cleaning the hole to prevent impurities and dust from entering the hole, thereby affecting the installation quality.
During the installation of the anchor bolt, it is crucial to ensure the tightening state of each component of the anchor bolt. Insert the anchor bolt into the cleaned hole and tighten it with a special tool. For mechanical expansion anchor bolts, special installation tools must be used to ensure that the anchor bolt can be fully embedded in the hole wall to form a firm anchoring effect. When tightening the nut, it is recommended to use a torque wrench and apply appropriate torque according to the specifications and model requirements of the anchor bolt to ensure the firmness and reliability of the connection.
During the installation of mechanical anchor bolts, the following aspects should also be noted. First, ensure that the drilling depth is appropriate so that the anchor bolt can expose enough threads after insertion to ensure a firm connection with the foundation. Secondly, when rotating the anchor bolt, be sure to ensure the accuracy of the anchor bolt position and avoid excessive rotation and force to avoid damage to the anchor bolt or the hole wall. For mechanical anchor bolts that require fillers (such as chemically cured anchor bolts), the operating procedures should be strictly followed according to the product manual to ensure the uniform distribution and curing effect of the filler.
