The Series 40 Through-Hole Molded-In Brass Insert is symmetrical which eliminates having to orient the Insert as it is placed onto the core pin in the mold. Series 40 Inserts are made from free-machining brass and are available to order in a range of inch threads from 4-40 to 3/8-16. Alternatively, SPIROL’s standard Series 63 Molded-In Inserts are made from 2024 aluminum, a lightweight, lead-free grade and offer superior resistance to torque and comparable pull out.

If you would like assistance in selecting the most appropriate Insert for your application, please contact SPIROL for complimentary technical support.
