Things To Be Aware Of When Applying Expansion Screws

We need to pay attention to the following things when making expansion screws:

1, the depth of the hole: the relevant information is the length of the expansion tube, but I found that this depth is not enough in the specific construction, may be related to the amount of debris residue in the hole, so you better be about 5 mm deeper than the length of the expansion tube. As long as you are greater than or equal to the length of the expansion tube, then the length of the expansion bolt left underground is equal to or less than the length of the expansion tube.

2, the expansion bolt on the ground requirements of course, the harder the better, it also depends on the force of the object you need to fix. The force strength installed in concrete (C13-15) is five times greater than in brick.

3. After the expansion bolt of M6/8/10/12 is correctly installed in the concrete, its least ideal maximum stationary force is 120/170/320/510 kg.

Warm tips: the performance of expansion screws is graded, we can choose different grades of screws according to our specific needs, so that the expansion screws can play the best role in the use of the process.
