The metric Series 30 Long Insert has the exact same body style as the metric Series 29 Long Insert - with the addition of a head. This is the longer version of the Series 30 Short for higher torque and pull-out resistance. Designed with a wide center knurl with two smaller knurls and deep undercuts on both ends, the Series 30 Long Headed Insert (and the symmetrical Series 29 Long) typically provides the highest torque and pull-out performance within SPIROL’s Heat/Ultrasonic style Inserts designed for straight holes. This series is symmetrical for ease of orientation, and the generous pilot facilitates installation into the hole. The Series 30 Long - Headed series is available in metric threads ranging from M2 up to M8.
