1、UDC 621 B2.6 DEUTSCHE NORM October 1992 EN Standard I Clevis pins with head (IS0 2341 : 1986) English version of DIN EN 22 341 DIN EN Standard This standard incorporates the English version of Is0 2341. Bolzen mit Kopf (IS0 2341 : 1986) European Standard EN 22 34 : 1992 has the status of a DIN Stand

2、ard. A comma is used as the decimal marker. Supersedes DIN 1444, March 1974 edition. National foreword The publication of this standard is in keeping with a decision made by CENTTC 185 to adopt, without alteration, a series of IS0 Standards covering clevis pins and washers for use with clevis pins a

3、s European Standards. The responsible German body involved in their publication is the Normenausschu Mechanische Verbindungselemente (Fasteners Standards Committee). As a consequence, all DIN Standards covering such pins and washers have been superseded by the corresponding DIN EN Standards (see tab
