Brass Threaded Inserts are precision-engineered fastening components designed to provide strong, wear-resistant, and reusable internal threads in plastic, wood, metal alloys, and composite materials.
These inserts offer excellent mechanical strength, corrosion resistance, and high pull-out performance, making them suitable for injection moulding, ultrasonic insertion, heat staking, press-fit, and cold installation applications.
