Needle used to meet the standard requirements of the GCrl5 bearing steel, hardness 61-65HRC, Needle according to size, shape, tolerance is divided into three levels of 2,3 and 5, followed by high to low precision.
In diemaking and precision tool design, where tolerances often split thousandths of an inch, it is critical that correct doweling methods and the right dowel pins be used. It is important to bear in mind that dowel pins should be employed for locating purposes and never to replace a screw for fastening purposes.
