NOTE: Normative references to international publications are listed in Annex ZA (normative). Page 3 EN IS
18、0 8739 : 1997 1 Scope This International Standard specifies the characteristics of full-length parallel grooved pins, made of steel or austenitic stainless steel, with pilot which have three equally spaced grooves impressed longitudinally on their exterior surface and a pilot to facilitate insertion
19、, with nominal diameter, d, from 1,5 mm to 25 mm inclusive. The displaced material to each side of the grooves forming an expanded diameter d2 which 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 nomina
20、l diameter d, (see clause 4). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parti
21、es to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
