Product description

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

The 1.4mm PCB inner-outer thread super screw was developed for 1.4mm-thick PCB boards; a high-efficiency deep-hole machining process creates a two-way fastening structure with an external thread at one end and an internal thread at the other. The external thread connects to the housing and the internal thread accepts a screw, enabling board-level stacking and fixing with good fatigue resistance, well suited to automated assembly.

Technical Features
Inner-outer bidirectional thread structure with one end joining the housing and the other locking the boardFits 1.4mm thick PCBs without deforming the boardEfficient deep-hole machining with high coaxiality and thread precisionPremium alloy steel: fatigue-resistant and suitable for repeated assembly/disassemblySuitable for automated assembly and bulk feeding
Applications
PCB assembly for telecom and server equipmentIndustrial control boardsPower modules and invertersConsumer electronics mainboards

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 1.4mm PCB Inner-Outer Thread Super Screw made of, and what strength level does it achieve?

Material specified in this page's specification table: premium alloy steel. Mill certificates and mechanical property test reports can be provided with the shipment; batch acceptance follows the specifications above.

Q2What applications is the 1.4mm PCB Inner-Outer Thread Super Screw suitable for?

Typical applications listed on this page: telecom and server PCB assembly; industrial control boards; power modules and inverters; consumer electronics motherboards. Overview: the 1.4mm PCB inner-outer thread super screw was developed for 1.4mm-thick PCB boards; a high-efficiency deep-hole machining process creates a two-way fastening structure with an external thread at one end and an internal thread at the other.

Q3What manufacturing process is used for the 1.4mm 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.

Q4What are the main features of the 1.4mm PCB Inner-Outer Thread Super Screw?

Features listed on this page: inner-outer two-way thread structure, one end connecting to the housing and the other fastening the board; fits 1.4mm-thick PCBs without deforming the board; high-efficiency deep-hole machining gives high concentricity and thread accuracy; quality alloy steel for fatigue resistance and repeated assembly.

Q5What does the 6g thread tolerance of the 1.4mm 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 "1.4mm PCB inner-outer thread super screw".)
