151286, M3.5-0.6x 7.138 Brass, Long, Straight Hole - Symmetrical-Headed Insert, Series 30

Brass and Aluminum inserts are used to preserve the threaded joint integrity for the life of the application. Inserts provide reusable threads and secure tight threaded joints.

These are the longer versions of the Series 29 & Series 30 Short metric Inserts for higher torque and pull-out resistance. The Series 29 & 30 Long Inserts are designed with a wide center knurl coupled with two smaller knurls and deep undercuts on both ends to maximize torque and pull out performance. The Series 29 Long is symmetrical for ease of orientation, and the generous pilot facilitates installation into the hole. The Series 30 Long has the exact same body style as the Series 29 Long - with the addition of a head for more bearing surface for the mating component to prevent jack-out. The Series 29 & Series 30 Long Inserts are available in metric threads ranging from M2 up to M8.
