| ①, The nominal diameter is equal to the diameter of the split pin hole. The recommended tolerance for pin hole diameter is: Nominal diameter ≤ 1.2: H13; Nominal diameter>1.2: H14 According to the agreement between the supply and demand parties, it is allowed to use split pins with nominal specifications of 3, 6, and 12mm. | ||||||||||
