Comprehensive Brass Inserts Catalog
Chetna Industries manufactures an extensive range of ISO Certified precision CNC brass inserts designed for diverse industrial applications. Our products are used in plastic injection molding, ultrasonic welding, heat staking, and press-fit installation — providing reliable threaded connections in plastic, rubber, wood, and composite housings.
Each brass insert is manufactured from high-grade free-machining brass (CDA C36000/C38500) and can be customized to meet your exact specifications. We offer standard metric and imperial thread sizes, custom diameters, special knurl patterns, and various surface finishes including natural, nickel-plated, and tin-plated options.
