Dutux Brass Self Locking Expansion Inserts (DBI-021) are specially engineered threaded inserts designed to provide secure and vibration-resistant fastening in soft materials such as plastic, wood, fiberboard, and composite materials. These inserts feature a self-locking expansion design with vanes, which expand during installation to create a strong mechanical lock inside the base material.

Manufactured from high-quality free cutting brass, these inserts offer excellent corrosion resistance, durability, and reliable performance in demanding applications. The expansion mechanism ensures a tight fit, preventing rotation and providing maximum pull-out resistance.

Dutux Brass Self Locking Expansion Inserts are widely used in plastic components, furniture fittings, electronics housings, and automotive assemblies. Custom sizes and specifications can also be manufactured as per customer drawings or samples.
