The DIN standards are recognized worldwide and used extensively in many industries, including engineering, manufacturing, and construction. In this article, we will discuss some of the DIN standards related to  machine screws, namely DIN 84, DIN 7985, DIN 85, DIN 963, DIN 965, DIN 964, and DIN 966.

DIN 84: This standard specifies the dimensions and tolerances of cheese head screws. Cheese head screws have a cylindrical head with a flat top and a flat bottom. The head has a larger diameter than the shank, which allows for a larger contact area with the surface being fastened. The screw has a straight slot for a screwdriver or a cross recessed slot. The dimensions specified in the standard include the diameter, length, head diameter, head height, and thread length. The tolerances ensure that the screws can fit into a corresponding nut or threaded hole.

DIN 7985: This standard specifies the dimensions and tolerances of pan head screws. Pan head screws have a rounded, dome-shaped head with a flat bearing surface. The head has a smaller diameter than the shank, which allows for a smaller contact area with the surface being fastened. The screw has a cross recessed slot or a hexagonal socket. The dimensions specified in the standard include the diameter, length, head diameter, head height, and thread length. The tolerances ensure that the screws can fit into a corresponding nut or threaded hole.
