We treat every order like the part is in the finished state. Each order is hand racked or loaded as to ensure the risk of damage is kept to a minimum. Whether the part is a .001 inch diameter ball or a much larger component part, we use the utmost care, exceeding the customers expectations. One of our greatest compliments is that many of our customers mention how the parts do not even look like they’ve been heat-treated because of how bright and shiny they are.
