Product description

Compiled from the existing technical description of this product on this site

The 1.2mm PCB inner-outer thread super screw is designed for 1.2mm thin panels and uses a precision inner-outer thread structure for two-way fastening: the external thread is fixed to the housing, the internal thread accepts a standard screw. A high-hardness alloy body and fine thread rolling give stable tightening and high pull-out resistance, effectively preventing PCB deformation under load.

Technical Features
Inner-outer bidirectional thread completes board-level stacking in one passDesigned for 1.2mm thin sheets, suppressing board deformationFine thread rolling: high thread precision and smooth tighteningHigh-hardness alloy with strong tensile strengthSuitable for automated assembly and bulk feeding
Applications
Mainboards for wearables and portable devicesCommunication modules and network cardsMicro power boardsCompact control boards

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the 1.2mm PCB Inner-Outer Thread Super Screw made of, and what strength level does it achieve?

Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.

Q2What surface treatments are available for the 1.2mm PCB Inner-Outer Thread Super Screw, and how to choose?

Surface treatment specified in this page's specification table: zinc / nickel plating (optional). Each coating differs in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q3What applications is the 1.2mm PCB Inner-Outer Thread Super Screw suitable for?

Typical applications listed on this page: wearables and portable device motherboards; communication modules and network cards; micro power boards; small control boards. Overview: the 1.2mm PCB inner-outer thread super screw is designed for 1.2mm thin panels and uses a precision inner-outer thread structure for two-way fastening: the external thread is fixed to the housing, the internal thread accepts a standard screw.

Q4What manufacturing process is used for the 1.2mm PCB Inner-Outer Thread Super Screw?

Thread rolling is specified as the process in this page's specification table. The process route follows drawing and order requirements; first-article approval is provided before volume production.

Q5What does the 6g thread tolerance of the 1.2mm PCB Inner-Outer Thread Super Screw mean?

6g is the standard tolerance class for external threads (GB/T 197 / ISO 965-1). It defines the manufacturing tolerance range for the pitch diameter and major diameter, balancing smooth engagement against manufacturing economy; the mating internal thread is usually 6H. All threads in this series are inspected to 6g. (Applies to model "1.2mm PCB inner-outer thread super screw".)
