The other characters are supposed to be A4-70, which is a material designation according to ISO 3506-1 Mechanical properties of corrosion-resistant stainless-steel fasteners -- Part 1: Bolts, screws and studs. This is an austenitic stainless steel (nominally type 316), with ultimate tensile strength of 700 MPa.
