BHT / BMT Series BEARHUG Locknuts – All-Metal, High Temperature

BHT (inch) and BMT (metric) are the all-metal BEARHUG locknuts. The polymer locking ring is replaced by an all-hardened-alloy prevailing-torque design, which lifts the maximum operating temperature from 160°F to 300°F. Use them wherever a standard BEARHUG nut would sit too close to a heat source for the polymer ring to survive.
