Key features

Special triangular self-locking thread design provides tight thread engagement, helping reduce loosening caused by vibration and impact while improving connection stability and reliability.

Available in round head, pan head and hex head configurations to meet different installation spaces, tooling requirements and assembly applications.

Zinc plated surface provides an additional protective layer against moisture and general corrosion, while offering a clean and uniform surface finish.

The self-locking thread increases friction and locking force between mating threads, providing a more secure connection in applications exposed to vibration and mechanical movement.

Precision thread machining ensures consistent thread dimensions and profiles, providing smooth engagement with nuts or threaded holes and reliable assembly performance.

The robust metal construction is designed to withstand normal assembly loads. Combined with the appropriate head design and self-locking thread, it is suitable for long-term industrial applications.

Suitable for machinery, automotive components, sheet metal, electronic equipment, industrial assembly, cabinets and engineering structures, especially where resistance to loosening is required.

Multiple head styles, sizes, thread specifications, lengths and surface finishes can be customized according to customer requirements, making the screws suitable for both standard orders and customize
