All SOFTERFIX™ open inserts for overmoulding incorporate exclusive CRUSHPROOF™ technology:
In using this type of insert, the cavity length should be slightly shorter than the dimension of the insert length, so as to ensure perfect sealing during moulding.
If this difference in dimensions is too great, the insert tapping may become damaged.
Exclusive CRUSHPROOF™ technology allows a torque differential of up to 0.5 mm, whilst maintaining thread function.
