The FSUK EXP range is designed around a diamond knurl configuration with a slot which enables the insert to expand when the mating screw is assembled. This insert is designed more for Thermosetting Plastics although can be used in some Thermoplastics. Available in a headed and reverse head; it is designed with an anti-vibration feature to stop the screw working loose after assembly. It's designed to be pressed in cold into drilled or moulded holes.
