Metric, Din 931, Steel self colour

A metric hexagonal bolt or hex bolt as it's commonly known, manufactured to Din 931. This partially threaded bolt with a plain shank and hexagonal head is ideal for heavy duty fastening applications, and usually installed with a spanner or socket tool. Manufactured in 8.8 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.
