3.5 mm Cortical Nut (sterile) [CN35]
This is the 3.5mm Cortical Nut for 3.5mm Cortical Screws. Occasionally tapped threads strip and a larger screw is appropriate. Lag screws are particularly vulnerable as only one cortex is available. A cortical nut manufactured from implant grade nylon gives the screw purchase allowing normal tightening. The thread form is designed to grip the screw to minimise backing out. Available in 2.0mm, 2.4mm, 2.7mm, 3.5mm and 4.5mm cortical thread forms. Supplied as a single sterile pack. The 4.5mm nut is also available in stainless steel.
