Mine-Safe Wheel Nuts keep your fleet safe and operational in the harshest mining environments — from underground headings to haul roads.
Mine-Safe Wheel Nuts for light vehicles use a 4 mm nylon insert with a SS420 stainless body to stop loosening in the harshest conditions — including hypersaline water exposure.

Real feedback from Australian mining operations using Mine-Safe Wheel Nuts on light vehicles.
“We were trialling the Mine-Safe Wheel Nuts on our underground fleet, using 4 OEM nuts and 1 Mine-Safe Nut per wheel. One of our LVs had a wheel come loose and the only thing holding it on was the Mine-Safe Wheel Nut. We’ve since rolled them out to multiple sites.”
“Simple swap-out. Significantly less damage to the LVs.”
