Metric, Din 933, Steel self colour

A metric hexagonal set screw or Hex Set as it's commonly known, manufactured to Din 933. This fully threaded bolt is designed for use in heavy duty fastening applications, and is ideal for installation into pre-threaded holes using a spanner or socket tool. Manufactured in 12.9 high tensile steel in a self colour finish, ideally suited for internal applications as it has no additional corrosion resistance. The colour of the bolt can vary from bright steel to black and will change over time due to oxidisation.
