J.Lanfranco locknuts have been trusted by mining operators for more than 40 years. The single piece all-metal design resists vibration, shock, and corrosion. Capable of being installed on standard bolts using standard tools, our THU locknuts will not damage bolts or succumb to seized nuts – even under the most extreme mining environments.
Don’t let extreme vibration, temperatures, and corrosion bring your mining operation to a grinding halt. We’ll help you minimize costly downtime and improve plant throughput.
Managing complex equipment for the oil and gas industry doesn’t have to be complicated. Using standard tools, our one-piece locknuts will ease installation and maintenance. Best of all: Absolutely no galling or seized nuts.
There’s very little room for error in military and defense applications. Mechanical failures can cost lives, so we rigorously test all our products under the harshest conditions to ensure there are no surprises.
Keeping trains moving; keeping passengers safe. That’s our goal. Operational efficiency and public safety means you can’t afford to take chances with safety critical bolting components. J.Lanfranco ensures you’ll stay on track.
