Bard part number 1012-211 is a 3/8-16 KEPS nut used throughout Bard wall-mounted HVAC equipment to secure brackets, panels, and mechanical assemblies where vibration resistance matters. A KEPS nut has a captive external tooth lock washer that helps maintain clamp load and reduces the chance of fasteners backing off in normal unit operation. Using the correct Bard OEM hardware helps protect alignment and serviceability, especially when replacing components or reassembling the unit after maintenance, so match the 3/8 inch diameter and 16 TPI thread to the original bolt or stud and confirm fit to your specific Bard model and serial number before ordering.
* Orders less than $50 may incure a minimum order fee.
