The series includes. ---GB/T 71 slotted tapered end set screws; ---GB/T 73 slotted flat end set screws; ---GB/T 74 slotted recessed set screws; ---GB/T 75 slotted long cylindrical end set screws; ---GB/T 77 hex flat end set screws; ---GB/T 78 hexagonal taper end set screws; ---GB/T 79 hexagonal cylindrical end set screws; ---GB/T 80 hex socket end set screws; ---GB/T 83 square head long cylindrical spherical end set screws; ---GB/T 84 square head concave end set screws; ---GB/T 85 square head long cylindrical end set screws; ---GB/T 86 square head short cylindrical cone end set screws; ---GB/T 821 square head flat end set screws. This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 74-1985 "grooved concave end set screws", compared with GB/T 74-1985, the main technical changes are as follows. ---The reference thread standard is unified to GB/T 193, GB/T 9145 (see Chapter 2, Table 2); --- Increase the thread size of M3.5 (see Table 1); --- Increase general technical conditions according to GB/T 16938 (see Table 2); ---The mechanical performance grade of stainless steel was modified to. A1-12H, A2-12H and A4-12H (see Table 2); --- Add non-ferrous metals CU2, CU3 (see Table 2); --- Increase the performance grade of steel and stainless steel screws "d < 1.6mm. according to the agreement" (see Table 2); --- For steel screws, remove surface oxidation treatment, increase the technical requirements of untreated and non-electrolytic zinc sheet coating according to GB/T 5267.2 (see Table 2); --- For stainless steel screws, remove the untreated, add simple processing and passivation treatment technical requirements according to GB/T 5267.4 (see Table 2); --- Add "If other technical requirements or surface treatment are required, the supply and demand agreement should be provided" (see Table 2); --- Increase the surface defects of steel screws (see Table 2).
