A Custom Fastener for the Mining Industry Shines Like Gold

Crafting just the right piece of hardware can sometimes feel like creating a piece of jewelry. And when custom bolts and nuts are needed to secure heavy equipment, absolute precision is necessary. A recent custom fastener we developed for hydraulic mining equipment both met the exacting tolerances of the blueprint and sparkled like a golden pendant thanks to its distinctive plating.

The client came to Chicago Nut & Bolt with an order to produce 2,500 custom pieces with several special features. First, the fastener had to be crafted from high-alloy hardened steel, which would provide considerable strength and resistance to corrosion. Because the mining equipment would be exposed to wet conditions, including ocean water, this high level of preservation was key. Second, the custom fasteners needed to feature internal and external threads so that they could be screwed both inside and out. Basically, it was a special nut and bolt combined in one piece.

Based on the client’s exacting blueprints, we began the process of filling this custom order by utilizing CNC machinery. Thanks to this advanced technology, the raw steel could be cut in a precise manner with a computer-controlled metal lathe. The CNC machine also added the interior and exterior threads to this special fastener. Next, the pieces were heat treated and finally plated, which created the gold sheen that makes the fasteners look like a modern piece of industrial-style jewelry. At each step in the process, our team performed a stringent quality inspection.

Finally, the 2,500 special fasteners were packaged to the customer’s specs and shipped. From blueprint to delivery, the process took about four weeks, although we have been known to create custom nuts and bolts as fast as overnight or within a few hours. That’s because our main capability is creating one-of-a-kind nuts and bolts in quantities from one to 1 million. Not every custom fastener we manufacture will look like a piece of jewelry, but every piece will always be just the right fit.
