Bard part number 1012-343 is an OEM 1/4-28 x 1/2 inch hex head bolt used as a factory fastener in Bard wall-mount HVAC assemblies, including economizer intake and exhaust damper hardware shown in Bard replacement parts documentation. When dampers, actuators, or brackets are serviced, using the correct Bard-specified thread and length helps maintain proper alignment and clamping force so moving components operate smoothly and stay secured under vibration. As a genuine Bard replacement fastener, 1012-343 is the right choice when you need an exact-match bolt for Bard equipment rather than a generic substitute.
