The Series 44 has the same body style as the Series 40 Through-Hole Moulded-In Insert, but in a blind ended version. Series 44 Blind-End Inserts are manufactured from free-machining brass and are made-to-order in a range of inch threads from 4-40 to 3/8-16. Alternatively, SPIROL’s Series 65 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.
