Here is one lot of app 500 pieces or 60 grams or 2.1 ounces gold plated circuit board contact or jumper pins. Supposed to be made by Circuit Assy Corp, part 11010-09. From late 80\'s. I do not have any spec sheets so do not know under lying material, thickness, etc. Non magnetic. They are app 7/16\" long by .024 thick. They are squarish. These are new old stock. No vendor packaging. A few minor blemishes from bulk storage. Unsure what circuit boards these will work with or fit. The # of pins is approximate. The weight is accurate. For shipping, will be placed in a small ziplok bag. I have several lots available. Free shipping via USPS package / box. If you have any questions, let me know please. Thanks.
