The Series 40 Through-Hole Moulded-In Brass Insert is symmetrical which eliminates having to orient the Insert as it is placed onto the core pin in the mould. 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 Moulded-In Inserts are made from 2024 aluminium, 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.
