Product description
Compiled from the existing technical description of this product on this site
Precision brass inserts are made of high-quality brass with excellent electrical conductivity and corrosion resistance. Multi-station precision turning and anti-slip knurling ensure a tight bond with plastic substrates, providing high pull-out strength and torque resistance. The thread tolerance is stable, making them suitable for plastic parts that require both threaded connections and electrical or thermal conductivity.

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 does the brass insert use? What strength level does it reach?
Specified in the specification table on this page: material brass (H62 / H59). A material certificate and mechanical property test report can be provided with the goods; batch acceptance is carried out in accordance with the above specifications.
Q2Which surface treatments are available for the brass insert? How do I choose?
Surface treatment specified in the specification table on this page: self-colour / nickel-plated / tin-plated (optional). Different coatings differ in appearance, corrosion resistance and cost; select according to the service environment and the order agreement.
Q3In which applications is the brass insert used?
Typical applications listed in the product description on this page: electronic connectors and terminal blocks; plastic housings for switches and relays; chargers and power adapters; automotive electronic plastic parts. Overview: Precision brass inserts are made of high-quality brass with excellent electrical conductivity and corrosion resistance. Multi-station precision turning and anti-slip knurling ensure a tight bond with plastic substrates, providing high pull-out strength and torque resistance.
Q4What manufacturing process is used for the brass insert?
The process specified in the specification table on this page is precision turning. The process route follows the drawing and order requirements; first-article approval is provided before volume production.
Q5When is the brass insert required?
When threads in soft base materials (aluminium, magnesium, cast iron, engineering plastics) wear and strip after repeated assembly and disassembly, or when the thread strength is insufficient to withstand the assembly torque, an insert is used to form a wear-resistant, high-strength internal thread in the base material. This is a common solution for thread repair and reinforcement. This is a functional explanation; for verification refer to GB/T 196 and GB/T 197. Data for this model is subject to the specification table on this page. (Applies to this model: “brass thread insert”.)
