RS PRO 431-Piece A4 Stainless Steel Cap Head Socket Screw Kit


From the trusted RS PRO brand comes this set of high-quality hex socket cap-headed socket screws. Socket screws are tightened using an Allan or Hex key, making them ideal for use in applications where externally wrenched fasteners are not practical because of a lack of space. Countersunk head screws are popular in precision-focussed applications as the hex cap head required less surface to counter-bore.


In this kit, you will find a range of 431 cap head socket screws with hex socket drives to be tightened by Allan or hex keys. The kit includes thread sizes of M6, M8, M10 and M12 with lengths ranging from 12mm to 50mm.


Features and Benefits


  • Button head hexagonal socket screws to DIN912 standards

  • A4 ’Marine Grade’ stainless steel screws

  • Supplied in a polypropylene case with a hinged lid

    • Applications


    The impressive strength of A4 stainless steel, also known as ’Type 314’ or ’Marine Grade’, makes it a versatile component material that can withstand very high levels of wear and tear. A4 Stainless provides the highest level of corrosion resistance, making it an excellent material for applications in which there will be contact with food, fresh water, or chemicals, as well as surgical implants and even underwater installations.


    Due to these attributes of Type 314 stainless steel, these machine screws are suitable for a wide range of applications, including:


  • Chemical equipment

  • Food & drug production equipment

  • Bearing plates

  • Heat Exchanger tubes

  • Pumps & valves

  • Underwater installations
