Product Description

Sunmao Aerospace is a professional leader China countersunk head screws manufacturer with high quality and reasonable price. Countersunk head screws are fastening parts, also known as flat machine screws, whose heads are designed as cones with different angles. The head of the countersunk head screws have tool tightening grooves, including straight, cross, hexagonal, plum blossom, pentagonal, etc., which allow it to be installed in a variety of ways. Unlike ordinary screws, the purpose of the design of countersunk screws is to keep the surface flat after the screw is installed. By hiding the head inside the object, the flatness of the surface of the object is avoided from being damaged by the protruding screw head. This type of screw is usually used in situations where the surface needs to remain beautiful or where friction or damage caused by the protruding screw head needs to be avoided.
