Further, when steel pins and stainless pins are generically called i
5、n this Remarks 1. Standard, they shall simply be referred to as the “pins“. The pins specified in the text of this Standard shall be in accordance with the taper pins class B specified in the text of JIS B 1352. 2. The pins which are not in accordance with the text in shape dimensions, taper precisi
6、on and surface roughness are specified in Annex as “taper pins with split of an old type“. When fixing a pin at the same section as the bottom of split as shown in Fig. 1 and opening the tip of split symmetrically by hitting, the pin shall not be broken at not larger than 60“ in opening angle or cra
