Generally, the head type of self tapping screw is not limited to:
countersunk self tapping screw, round head self tapping screw,
large flat head self tapping screw, outer hexagon and inner hexagon
self tapping screw, double head screw, etc. (peripheral
accessories: gasket, screw cover, rubber ring, hook, etc.) to avoid
the use of quick teeth (sharper wood screws) to avoid cutting the
expansion tube when the screws are forced. It is suggested to
install and use self tapping screws to give full play to the best
friction and achieve the best tightening effect. Generally, the
