The invention discloses a nut production process. The process comprises the following steps that S1, through a casting process, a workblank part is made, and the workblank part comprises, by weight ratio, 0.28 to 0.32 of C, 0.32 to 0.45 of Mn, 0.05 to 0.09 of Zn, 0.15 to 0.25 of Si, 0.01 to 0.03 of La, not larger than 0.015 of P, not larger than 0.015 of S, 0.50 to 1.20 of Ni, 0.15 to 0.25 of Sn,0.15 to 0.25 of Al, 0.2 to 0.5 of Mo and the balance iron; S2, the workblank part is put into a mold cavity, cold heading extrusion molding is carried out, and the nut workblank is made; S3, the nut workblank is turned and tapped; S4, heat treatment is carried out; S5, surface treatment is carried out, cleaning oil removal is carried out, blackening treatment is carried out, static electricity manner is adopted to spray an anti-corrosion agent to the nut, and the sprayed nut is cured to obtain a nut finished product. The nut produced through the nut production process has the hardness value and strength value needed by the high-strength nut, is not prone to being corroded and long in service life.
