The robust design of the Series 60 Blind-End and Series 61 Through-Hole inserts consists of axial grooves to maximise torque resistance, balanced with radial undercuts to achieve high pull out force. These moulded in inserts are designed to be placed in the mould cavity prior to plastic injection, and offer exceptional performance due to unrestricted plastic flow into the retention features on the outside diameter of the inserts.(…)
