The invention discloses a steel wire rope and a production process thereof and relates to the field of hoisting with an aim to solve the problem that an existing steel wire rope cannot adjust self-tension according to different loads. The technical scheme includes that the steel wire rope comprises two strand wires twisted by multiple steel wires, connectors respectively fixedly connected to one ends of the steel wire ropes, connecting threads arranged on the connectors with backward helical direction and adjusting sleeves sleeving the connectors; two adjusting threads respectively matched with the connecting threads on the connectors are arranged in the adjusting sleeves; the production process of the steel wire rope includes the steps of 1), round steel pickling; 2), zinc-series phosphating treatment; 3), hole shrinkage; 4), galvanizing; 5), stranding; 6), laying up; 7), cutting off; 8), knitting of wire line hitches; 9), external thread lathing; 10), connector mounting; 11), internal thread lathing. The steel wire rope can adjust self-tension according to different loads during use.
