The four stands under the machine are M10 headless bolts. Made from the steel type 9SMnPb28K. With a length of about 100mm.
They have a strength class of 5.8. This means the ultimate tensile strength is 500N/mm² and a yield point of 400N/mm². (500 x 0.8)
The amount of pressure the stands deliver to the ground. One stand has a diameter of 50mm. The machine weighs 400kg.
surface area: 25².pi = 1963,5 mm²
weigth force : 400 . 9,81 = 3924N -> divided over the 4 stands = 981 N / stand
One stand gives 0,5 N/mm² pressure to the ground or 499619,2 Pa.
