Metric Socket Countersunk, Din 7991/ISO 10642, A2 (304) Stainless Steel

These socket countersunk screws are made out of A2 304 stainless steel material to Din 7991 with metric coarse thread.  Measured from end to end.  They are also known as FHSC (Flat head socket caps) or SKT CSK.  The screw is designed to be seated into a countersunk hole, providing a flush finish.  A hex key ( sometimes referred to as an Allen wrench of Allen key) or hex driver is required to tighten or loosen a socket screw.  Socket screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or spanner.  Please note that not all socket countersunk screws are fully threaded, if thread length is critical please contact us for more info.
