The Series 44 has the same body style as the Series 40 Through-Hole Insert, but in a blind-ended version. Series 44 Inserts are available in metric threads ranging in size from M2.5 to M10. Alternatively, SPIROL’s standard 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.
