Product Description
Because the half tooth screw has a section of light rod, and the light rod position relative to the thread part, with the preset hole more closely, the locking stability is high, and in the action of the shear force, the longer the object of the fastener is less likely to shift. If the object fastening effect requirements are more strict, can not have a little loose case, it is recommended to use half tooth screw. And the rod diameter strength of the half tooth screw is higher than the whole tooth screw, and the yield strength is also a little higher. If there is a requirement for the strength of the screw, it is recommended to choose the half tooth.
