Din 931 indicates partially threaded hex head cap screw ¨C The DIN 931 standard will specify the thread tolerance. ? M16; diameter in mm (16 mm) ? In the metric system, all fasteners are assumed coarse thread unless another thread pitch is stated.
Monel nickel-copper alloy K-500, combines the excellent corrosion resistance characteristic of Monel alloy 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanimum to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated thoughout the matrix.
