Brass Expansion Insert
Brass Expansion Insert
DBI-003
Strong and dependable internal threads in plastic, wood, and other soft materials are provided by brass expansion inserts, which are precisely constructed threaded inserts. During installation, these inserts expand to provide a firm and stable grip inside the base material. High pull-out resistance and long-term loosening are guaranteed by the expansion design.
These inserts, which are made of premium free cutting brass, have outstanding mechanical strength, longevity, and resistance to corrosion. When robust and reusable threads are needed, brass expansion inserts are frequently utilized in the plastic molding, furniture, electronics, and automobile industries.
Based on client designs or samples, we produce Brass Expansion Inserts in both conventional sizes and customized dimensions.
