• For nominal length l over 200 mm, the increment is 20 mm.

Continuation of Table 1

mm

4. Application

The hole for the pin is set equal to the nominal diameter of the pin d₁. The hole tolerance is H12. When installed in the minimum permissible hole, the slot of type A and type B pins must not close completely.

5. Technical requirements

Slot	Type A	The configuration and width of the slot are determined by the manufacturer
		Type B	The configuration and width of the slot, which does not guarantee the pin is locked in the hole, are established by agreement between the customer and the manufacturer
Material		Steel at the manufacturer’s discretion:
		any carbon steel with a content of:		or silicon-manganese steel with a content of:
		C>0.65%		C>0.5%
		Mn>0.5%		Si>1.5%
				Mn>0.7%
		hardened and tempered to a Vickers hardness of 420-520 HV or austenite-hardened to a hardness of 500-560 HV		hardened and tempered to a Vickers hardness of 420-500 HV
		Other materials - by agreement between the customer and the manufacturer
Coating		Pins should be manufactured without a coating. A coating may be applied by agreement between the customer and the manufacturer. Hydrogen embrittlement is not permitted. Tolerances on pin dimensions are valid prior to coating application
Surface quality		Burrs, cracks, scale, and corrosion are not permitted on the surface of the pins
Shear test		Per GOST R 50076
Acceptance		Per GOST 17769

6. Designation
