| Organization: | NEN |
| Publication Date: | 1 October 1992 |
| Status: | inactive |
| ICS Code (Pins, nails): | 21.060.50 |
scope:
This Standard specifies the characteristics of third-length centre grooved pins which have three equally spaced grooves impressed longitudinally on their exterior surface, with metric dimensions and nominal diameter, d1 from 1,5 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 d1 will cause a positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d1.
