A cross grooved countersunk head self-tapping screw is a self-tapping screw with a flat head, countersunk head or semi-countersunk head design, usually with a cross groove. This screw does not need to be used with the nut, and can directly tap into the material to form a thread and lock.

Material and specification

Cross slot countersunk head self-tapping screw material variety, common stainless steel 304, 410 and carbon steel. Stainless steel 304 has a lower hardness, while 410 stainless steel has a higher hardness, which is suitable for applications requiring higher strength. Carbon steel can be hardened by carburizing.

Application field

Cross slot countersunk head self-tapping screws are widely used in electronic appliances, rail transit, wind power generation and other fields. Due to its self-tapping properties, this screw is particularly suitable for the connection of metal materials, and can be threaded directly on the material and locked without the need for pre-drilling.

Performance characteristics

Features of cross recessed countersunk head tapping screws include:

Self-tapping capability: The ability to create threads directly on the material without prior drilling.

Good locking effect: The internal thread is formed in the hole through extrusion to form a reliable locking connection.

Various materials: Provide stainless steel and carbon steel and other materials to meet different strength needs.

Widely used: suitable for electronic appliances, rail transit, wind power generation and other fields.
