Seal Screw Series

Seal screw is a kind of machine screws inserted with o-ring underneath. The screws have prefabricated grooves under the head to embed in o-ring to form a comprehensive seal, avoiding any gas, liquid or dust leakage from the gap between the screw and the fastener and thus affecting the service status of the work piece.

Due to its excellent leak proof design, this screw is widely used in fields such as petrochemicals, electronic appliances, semiconductors, and food processing.

Thread Type : A straight shank fastener with external threads designed to travel through a hole or nut that’s pre-tapped to make a mating thread for the screw.
