pan head phillips O-ring Waterproof Sealing Machine screw
Description
There is an o-ring under the head of the sealing screw, which has strong sealing property, remarkable waterproof effect, environmental protection, harmless, high and low temperature resistance, good tear resistance, elasticity, hardness, insulation, and can prevent water, air and dust from entering the screw and play a protective role.
The pan head is slightly curved with low, large diameter and high outer edges. The large surface area enables the slotted or flat driver to easily grasp the head and apply force to it, which is one of the commonly used heads. The pan head cross screw can be used for different sealing requirements. We can provide cost-effective screws that meet the corresponding waterproof grade for different use environments.
