It depends on how strong the threaded material is. ISO 898-1 is a standard for mechanical properties of bolts, screws, and studs. For a standard M36 x 4 coarse pitch thread, the minimum proof load for a property class 10.9 fastener is 678,000 N. That is about 69000 kg after dividing by acceleration due to gravity to convert force to mass. You can increase that to 718,000 N by using a fine pitch (M36 x 3). Property class 10.9 is obtained by heat treating (quench & temper) suitable steel grades.
If you use the lowest strength, non-heat treated grade (property class 3.6), then the proof load drops to 147,000 N for coarse and 156,000 N for fine.
