Case Study: Large Industrial Rental Chain

We saved a national rental chain $5,675 in repair costs and 16.5 hours of downtime for each crane boom repair required. Nationwide, they averaged 2 repairs per week, resulting in over $500,000 savings and 1,716 hours of uptime annually on only one repair job out of many.

Happy Customers with Rotary Thread

We weren’t kidding when we told you that Rotary Thread can fix damaged thread of any kind. This tool can be used in fixing threads for every aspect of work. See it in action from our customers.

We Build Everything

Lewis Products (the umbrella company for Rotary Thread®), invented and markets the world’s only rotary thread® file. The tool was invented out of necessity. Years of experience in maintenance repair. All the methods of thread restoring were going to take far too long, too aggravating, and were too costly on downtime for our customers. So with an idea and a few prototypes later, a new tool category had formed. Rotary Thread® Files.
