Grooved pins with round head, Endorsement notice The text of the International Standard IS0 8746 : 1997 was approved by CEN as a European Standard without any modification. Page 3 EN IS0 8746 : 1997 1 Scope This International Sta

16、ndard specifies the characteristics of round head grooved pins which have three equally spaced grooves impressed longitudinally on their exterior surface, with nominal diameter, d, from 1,4 mm to 20 mm inclusive. The displaced material to each side of the grooves forming an expanded diameter, d2, wh

17、ich is larger than the nominal diameter d, will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d, (see clause 4). 2 Normative references The following standards contain provisions which, through reference in this text, constitute

18、 provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the s
