Product Description

Stainless steel countersunk screws with hex-drive head.  Manufactured from A4-70 (marine-grade) stainless steel, these screws will not suffer from rust stains.  These stainless steel countersunk socket screws are made to DIN standard 7991.  This standard does not define that they should necessarily be fully threaded, wherever possible we obtain fully threaded versions (set screws).

These stainless steel screws are ideal for deck fittings such as cleats and fairleads.   Use our penny washers underneath when using screws to attach load-bearing fittings. We would normally recommend Nyloc nuts for added security and resistance to any possibility of loosening under vibration loading.

When choosing the size and length of these stainless steel countersunk socket screws please ensure that the diameter is a correct match for the fitting.  This is usually determined by the hole size in the fitting.

Typically the hole size in the fitting has a diameter just over-size (eg 5.3mm for an M5 fixing).  Also bear in mind that all metric threaded bolts and fastenings are actually manufactured just under-size, so an M6 bolt or set screw will always fit through a 6mm drilled hole.
