DIN 84 M10 × 60 Cheese head
DIN 84 M10 × 60 is a cheese head screw with a 60 mm nominal length, on a M10 × 1.25 mm metric thread. A cylindrical head with a straight slot drive. Still common in instrument and electrical work, though pozidriv and hexalobular drives have largely replaced it in volume assembly.

DIN 84 is catalogued with ISO 1207 as its equivalent designation. Dimensions are compared field by field rather than assumed identical.
Choosing and fitting this size
DIN 84 M10 × 60 is a cheese head in M10, 60 mm long under the head, on a 1.25 mm coarse pitch. Mating threads should be a matching class nut or a tapped hole of the same nominal size.
Common stock grades are 8.8, 10.9 and 12.9 in steel, plus A2-70 and A4-80 in stainless. Class 10.9 and 12.9 carry roughly 1.25 and 1.5 times the proof load of 8.8, but they also need a properly rated mating nut — a class 8 nut under a 12.9 bolt simply moves the failure into the thread. Zinc-plated 10.9 and above should be baked to avoid hydrogen embrittlement.
For a tapped hole, M10 × 1.25 mm takes a 8.75 mm tap drill, and the external thread's minor diameter is 8.47 mm — that is the section carrying the load, not the nominal M10 figure. Thread engagement of at least one times the nominal diameter is what lets the bolt fail before the thread strips.
