FOR DRILLING It seems that the most popular pins are 1/8" in diameter although pins of 3/16"and 1/4" are sometimes used. These pins most often come in lengths of 3/8", 1/2", 3/4" and 1". We maintain substantial inventories of dowel pins in all of these popular diameters and lengths. In the 1/8"
diameter category, we offer both "Dowel"
pins and "Tooling"
pins at the same low price. |
 |
Dowel Pins are nicely rounded on one end while the other end is only slightly tapered and bluntly cut off. They are"Case Hardened" (hard on the outside and substantially softer on the inside.) They can bend or "Mushroom" when struck. |
 |
Tooling Pins are nicely rounded on both ends. They are "Through Hardened" (hard inside and out.) We normally recommend tooling pins over Dowel Pins but have customers for both and thus carry extensive inventories of both. |

Step Pins: Some circuit board manufacturers wish to employ the 1/4" lamination holes to set up their drilling; however, they do not wish to chew up their soft tooling plates with 1/4" holes. Our Step Pins answer this need by having a 1/4" diameter on the top and 1/8" diameter on the bottom. |
 |
Tack Pins: Still other circuit board manufacturers, particularly "Flex" shops, order pins that look like thumb tacks with 1/4" diameter head with a .030" thickness on a 1/8" diameter pin in a variety of lengths. |
