This Interscrew is comprised of a 10mm M5 captivated nut and 20mm raised countersunk machine screw. Both parts are manufactured from a high quality stainless steel.
Interscrews can be used for fixing windows and holding Aluminium frames onto the side of a cabin on your boat. The knurled nut press fits into the Perspex or frame to prevent it from turning. It does not have a slot to minimise tampering from the outside.
Other sizes of machine screws are available with a MOQ. Please enquiry for further information.
