Know Your Nuts and Bolts Inside and Out.
Many of the problems that challenge fastener reliability in the industry today come from a lack of knowledge about the bolts and their history. Parts are purchased by one company, sent to another for coating, are coated by hand, then shipped in boxes with no protection or consideration for bolt integrity. The boxes may contain markings that relate back to the partís origins, but the fasteners inside are not identified. When the bolts inevitably fail, there is no way to know which applications are currently using bolts from the same batch so they can be pulled from service, burdening the turnaround team with the responsibility of replacing the bolts as quickly as they can under stressful conditions that lead to simple yet costly mistakes.
This has been the way the industry has operated for decades. While some companies may be able to trace a bolt back to the manufacturer, for the most part their path from manufacturer to application is lost entirely upon leaving the box. When they can be traced back, they usually can only be traced to the manufacturer rather than the actual facility where they were originally made. And the coating process is never traced.
However, it doesnít have to be that way. The industry has possessed the technology to provide certainty and traceability for years, and with experts calling for change and developing new specifications to account for the need for traceability, a traceable fastener is the way of the future.
The Journey of a Fastener: Where it Is, Where itís Been, and Where itís Going
For Doxsteel Fasteners, traceability starts at the nut and the bolt. Each part is stamped with a marking that corresponds to its heat load and coating batch. This information allows our customers to reference the fastenerís Material Test Report (MTR) and track the parts as they work in the field. When coupled with our Fastener End of Life Test (FELT Test), customers are continually in the know about how the fasteners are performing. And when they near the end of their life cycle, this number will tell you at a glance which parts require immediate turnaround before they seize so you can avoid the issues associated with corrosion. We promise to deliver the most reliable fasteners that do not require hot bolting, and this promise rests partly on our unparalleled level of traceability.
