Brass Expansion Insert
Brass Expansion Insert
DBI-003
Brass Expansion Inserts are precision-engineered threaded inserts designed to provide strong and reliable internal threads in plastic, wood, and other soft materials. These inserts expand during installation, creating a tight and secure grip inside the base material. The expansion design ensures high pull-out resistance and prevents loosening during long-term use.
Manufactured from high-grade free cutting brass, these inserts offer excellent corrosion resistance, durability, and high mechanical strength. Brass Expansion Inserts are widely used in plastic molding, furniture manufacturing, electronics, and automotive industries where strong and reusable threads are required.
We manufacture Brass Expansion Inserts in standard sizes as well as customized dimensions based on customer drawings or samples.
