cheese head screw are easy to break and can do this

The quality of the screws produced by different screw manufacturers is different. Some pan head screws produced by screw manufacturers are relatively easy to break, so how can we improve the situation that the cheese head screw are always broken?

The choice of the material of the screw is generally the basis for determining the quality of the cheese head screw. The professional screw manufacturer has strict control on the selection of the screw. When the R head is placed under the head of the pan head screw, the R angle is too large or too small, which may cause the screw to break.

In addition to the structural factors, the above is used. For the hardness selection of the pan head screw, it is also important that the hardness is within the reasonable use range. The problem of hardness and torsion is removed. When we use more than the force that this screw can withstand, it will also break.

When the material of the cheese head screw is carbon steel and the strength requirement is very high, it is generally necessary to remove hydrogen. When the screw is not completely dehydrogenated, the screw will also be broken.

Of course, the above scheme is for reference only, and the use of most pan head screws is in the mold matching, screw structure, material selection, and the like. Regarding the problem of broken ends used by screws, it is still necessary to judge according to the actual situation. If the above methods are not improved, then you need to consider other reasons
